Sig Sauer P320

When you think of Sig Sauer pistols, you think of classic double/single-action. Or single action like the new P938 and classic 1911s. Or maybe that Double Action Kellerman (DAK) design. What you don’t think of is striker-fired.

While the new P320 clearly inherits some ideas and inspiration from the modular Sig P250 design, the action is all new. It’s a constant action, striker-fired pistol, complete with the internal safeties you would expect in a striker design.

Being a .357 Sig caliber nut, I just had to try one out in that caliber.

In the box

The model tested was chambered in .357 Sig. Note the brass stains.

The model tested was chambered in .357 Sig. Note the brass stains.

This Sig Sauer P320 chambered in .357 Sig came with two (14) round magazines. Additionally, Sig includes an outside-the-waistband Kydex paddle holster. The holster is marked “P250 Full Size” and “P250 Compact” which implies holster compatibility across those models. The holster includes a retention screw to adjust the tension to your preference. The lockable hard case also includes owner’s manual, a cable-style gun lock and a small tube of Sig Sauer Mil-Comm TW25B lubricant and protectant.

A quick and dirty tour

The slide release lever is not exactly ambidextrous, there are actually two of them already in place, one on either side.

The magazine release button is, in fact, ambidextrous. By default, it’s on the left side of the pistol. It’s easy to reverse to the other side, again without specific tools. A paper clip is all you really need to release it from the grip model and reinstall on the opposite side.

The sights are SigLite with tritium inserts and they’re made of steel so you can rack this gun on a belt, boot or hard surface without worry should the need arise.

There are slide release levers on both sides.

The magazine release button can be moved to the opposite side.

The magazine release button can be moved to the opposite side.

Following the steel parts theme, the magazines are also made of steel. They drop freely when released, but seat with equal ease. No encouragement is required to lock them in place. The guide rod is also made of steel.

The first thing I do with a new pistol is press the trigger – a lot. I worked this one quite a bit and found it to be – awesome. For a striker-fired pistol, it’s smooth and crisp. A brief take up is followed by short travel of constant pressure and a clean break. The reset is positive and very easy to feel if you’re into that sort of thing. I measured the press weight at six pounds, although it felt lighter.

Internal safeties prevent the striker from firing unless the trigger is pulled. Another locks the striker if the slide is out of battery.

Internal safeties prevent the striker from firing unless the trigger is pulled. Another locks the striker if the slide is out of battery.

As a classic striker-fired gun, there are no manually operated external safeties. However, that doesn’t mean there aren’t internal safety systems in place to help prevent unintended discharges.

An internal striker safety locks the striker in the back position until the trigger is pressed all the way to the rear.

A disconnect safety prevents the P320 from firing when the slide is out of battery. With everything unloaded and the magazine removed, I tested this out by pulling the slide back a fraction of an inch then pulling the trigger. Sure enough, the striker didn’t release.

A three-point take down safety design ensures that the takedown process won’t work until the slide is locked to the rear, the magazine is released, and the slide can be removed without need of pressing the trigger.

The standard P320 does not need a tabbed trigger insert to provide drop safety. However, if you want that, it’s available as an option. The P320 also, by default, will fire without a magazine in place. If you prefer the opposite scenario, you can order the P320 with a magazine safety. I think it’s interesting how the Sig folks have taken full advantage of the modular design and side-stepped those issues that upset people so much. Like a magazine safety? Great, buy it that way. Hate that? Great, buy it that way. It’s hard to go wrong when you give customers what they want.

It’s a gun, but not exactly…

When you look at what most would consider the “frame” of the Sig P320, you’ll see all the normal stuff: grip, trigger guard, mil-spec M1913 rail up front and a cutout on the right side that shows the serial number. But wait! That’s not actually a frame, it’s just a part. You can buy one wherever you like and without a background check. You can even order one online and have it shipped to your house.

The frame of the P320 is actually the fire control assembly, which the grip module is an inserialized part.

The frame of the P320 is actually the fire control assembly, while the grip module is a serialized part.

Sig calls the firing system the frame. Think of the “frame” as the firing control system – trigger and internal safeties. The striker itself resides in the slide assembly. The frame also includes four stainless steel slide rail guides, two on each side, front and back. In addition to being able to change grip modules, you can also change caliber by adding the appropriate slide and barrel to the frame. Right now, the P320 is available in 9mm, .357 Sig, and .40 S&W. Soon, there will be a .45 ACP option too.

By swapping parts around the frame, you can change the size of the hole in the fiery end.

By swapping parts around the frame, you can change the size of the hole in the fiery end.

While that sounds nifty for shopping convenience, there’s a good reason that the “frame” is not really the frame. The collection of mechanical stuff that’s defined as the serialized gun is contained entirely inside of the frame, and you can take it out without the aid of hammers and such. The idea behind this modular design is that users (individuals or perhaps military and law enforcement agencies) can configure each pistol to different specifications. My test P320 came with a “Full Medium” grip module. That means the grip circumference is the medium size, but the “frame” (read grip module) is full-length and full height. If I want, I can order a smaller grip module and slide assembly that will convert my P320 to a compact carry gun. Instead of the replaceable backstop approach used by many gun makers, Sig offers entire grip modules in small, medium and large circumference sizes. No parts to move around – it’s a solid configuration as the entire grip module (frame) is a single piece.

The grip has cutouts for manual magazine access if needed.

The grip has cutouts for manual magazine access if needed.

I’m thinking that small, medium and large grip sizes don’t mean much to you without some point of reference, so let’s try to provide that. The one I have here has a medium grip size. Measuring the circumference with a tape, I come up with about 5 5/8 inches at the widest spot. That’s almost exactly the same as the grip circumference on my FNS-40 with standard back panel, Beretta Px4 with medium grip panel, and Glock 31 Gen 4 with no back panels installed.

Frames also come in different overall sizes (not just grip circumference) and right now you can get a full size, carry or compact version. Matching slide assemblies are required for some combinations. Soon, Sig intends to release a subcompact grip module and slide assembly. Here’s a summary of the dimensions of the four different grip module and slide assembly options.

Sig Sauer P320 specifications

With this design, there are lots of options, and you can bet the list of available configuration pieces and parts will only grow.

Let’s take this thing apart

Before I even talk about field stripping procedure or how to swap out grip modules, I should mention a huge feature. You can take down the P320 without pulling the trigger or performing any type of trigger release. Just remove the magazine, lock the slide back, rotate the takedown lever and the slide will move right off the front of the grip module. It couldn’t be simpler and I liked that you don’t have to pull the trigger or manipulate any internal parts before takedown.

Sig Sauer P320 357 Sig-3

A full takedown, required to change grip modules, for example, isn’t much harder. To completely remove the frame from the grip module, start with the normal takedown procedure. Once the slide is removed, simply pull the takedown lever completely out of the grip module, much like you remove the slide release lever on a 1911. Once the takedown lever is completely out, the frame lifts right out of the grip module. No tools and the whole process only takes a few seconds. The best part is that there are no small or loose parts, so there is no risk of “having parts left over” after reassembly.

The most interesting part of the design, apart from the fact that everything can be done without any tools, is that the internal frame and slide assembly are the pieces that lock together. How the frame fits into the grip module really doesn’t have an impact on accuracy. That’s a good thing, as the grip module is made entirely of polymer. More on that later.

Shooting the P320

I quickly learned to use these depressions for my firing hand thumb to keep it out of the way of the slide release lever.

I quickly learned to use these depressions for my firing hand thumb to keep it out of the way of the slide release lever.

I shot a broad array of factory .357 Sig ammo through this gun and none of my wimpy hand loads for that caliber. I figured if I was going to run it through accuracy, velocity, and handling testing, I was gonna go with all full-power .357 Sig loads. You know, the ones that the cartridge was designed for to approximate the storied 125 grain .357 Magnum.

The first thing I noticed was the value of a really, really nice grip. The P320 grip feels much like the new one-piece grips on the P226 and P229 models. If you envision a cross section, it’s more of an oval shape than many of the square forms out there today. For me, this results in much more hand-to-grip surface contact and that makes a big difference in felt recoil and ability to control the pistol. I shot this P320 side-by-side with a Glock 32 and Glock 31, both also chambered in the stout .357 Sig caliber, and the comfort of shooting the P320 was far better. My theory is that the squared grips of the Glocks allow the pistol to move around in the hands more as less of the grip surface contacts your fingers and palm.

No hammer!

No hammer!

You’ll notice that both sides of the grip module have a curvy recess above the magazine release button. Use this for your thumb. When I first started shooting the P320, I assumed a high thumb grip similar to how I shoot a 1911. I didn’t really think about the fact that the slide release lever was right in the neighborhood of my raised thumb until I noticed the slide was not locking back after the magazine ran dry. That just might have had something to do with my thumb pressing downwards on the lever. Do the responsible thing – put your thumb in the provides holes and all will be well.

One more thing I noticed while shooting. The bottom of the grip has a cutout on both sides just over the magazine base plate. Presumably, this is to aid manual extraction of the magazine in the event of a jam. The cutouts don’t interfere with your grip but do offer a solid grasp on the magazine if you do need to yank it out with brute force. I didn’t have any jams in the hundreds and hundreds of rounds I fired. That’s one of the things I really like about the .357 Sig caliber – the bottleneck cartridge feeds very, very reliably.


Sig Sauer P320 Accuracy and VelocityFor me, most of the challenge of shooting perfect groups at 25 yards is sight picture. The very slightest of misalignments between the sharp front sight, blurry rear sight, and blurry target can easily translate to a good chunk of an inch (or more) at 25 yards. For that reason, I decided to accuracy test the Sig P320 with a new system I’m testing.


I installed a UM Tactical UM3 Sight Mount. This mount attaches to the M1913 rail in front of the trigger guard, wraps around both sides of the frame and slide, and provides a rail segment above the pistol for an optic or handgun scope. It’s a neat idea and does not interfere with semi-automatic operation.

For my optic, I consulted the gurus at Bushnell. After talking about the scenarios I wanted, we decided on a Bushnell Elite 3500 Handgun Scope. This model is a 2-6x variable with a 32mm objective lens. While it can certainly help you reach out much farther than 25 yards, the variable zoom was perfect for getting a great sight picture at my accuracy testing distance. The reticle is a Multi-X design that offers thick crosshairs that narrow to hair width in the center area. This arrangement gives you precision at the aim point while helping guide your eye quickly to the center of the viewing area.

I used this UM Tactical optics mount and a Bushnell Elite 3500 Handgun scope for accuracy testing.

I used this UM Tactical optics mount and a Bushnell Elite 3500 Handgun scope for accuracy testing.

I shot several boatloads of 5-shot groups with this arrangement and was pleasantly surprised by the accuracy of the P320. In many cases, it even out shot a Sig Sauer P226 .357 Sig that I was using as a comparison. I didn’t expect this result from a polymer frame (sorry, I meant polymer grip module) handgun. The P320’s ability to shoot small groups with a variety of ammo told me that the grip module, frame, and slide assemblies lock together perfectly. Remember, the optic in this scenario was mounted to the polymer grip module and not the slide assembly which you would expect to offer repeatable accuracy. I was impressed.

If you dig .357 Sig, you’re probably a believer in the value every last bit of velocity. After all, the whole point of the .357 Sig caliber is to more or less replicate the performance of a 125 grain .357 Magnum round. Those move at 1,400 to 1,500 feet per second and many believe that’s why it’s been such an effective cartridge over the years.

I tested a bunch of loads for velocity using a Shooting Crony Beta Master chronograph placed 15 feet downrange from my shooting bench. The P320 didn’t disappoint, especially when using Doubletap Ammunition .357 Sig loads. The Godfather of Boom!, Mike McNett, runs Doubletap and he believes in extracting every last bit of performance out of the cartridges he loads. It shows.

Most of the loads shown here were also tested with a Sig P226 and almost without exception, the P320 added a bit more velocity, usually 20 to 30 feet per second. That’s almost certainly a result of the extra .3 inches of barrel length on the P320. The P320 has a 4.7-inch barrel while the P226 has a 4.4-inch barrel.

Parting Shots

I’ve got three different models of Sig Sauer pistols in for various reviews and all are chambered in .357 Sig: a Sig P226, P229 and the P320 we’re talking about here. Going into this project, I figured I would love the P226 and P229 and be OK with the P320. It’s a largely polymer gun after all and how can that compare to the classic “steel feel” of the P226 and P229?

I’m trying not to draw comparisons because we’re talking about apples and oranges, except that they share the same caliber, in this case. The most obvious difference is the traditional DA/SA action of the P226 and P229 versus the striker-fired action of the P320. To me, that’s not a better / worse comparison, it’s a personal preference. Being a gun guy, I like both systems for different reasons. The transition from double-action to single-action doesn’t bother me and I kind of like the peace of mind that a first double-action shot offers. On the other hand, I’m not the least bit nervous about carrying a striker-fired gun with a constant, and lighter, trigger press.

The P320 includes SIGLITE steel tritium sights.

The bottom line is that I was very pleasantly surprised with the P320. The accuracy shocked me given its modular construction and polymer grip module. Now I’ve got this idea of keeping it, acquiring a threaded barrel (that’s a P320 option too) and adding a suppressor. Clearly the .357 Sig is not intended to be used with subsonic ammo, I just think it would be a great shooting combination – just like using a suppressor on a hot 9mm pistol. Losing the muzzle blast, even when shooting supersonic ammo, is a really cool shooting experience.

Consistent with my assumptions going in, I figured I would end up sending Sig a check for the P226 and P229 so I could keep them. Now I’m not so sure I won’t be purchasing the P320. Sorry, GunsAmerica Editor Dave, I call dibs.

    Will SIG ever get around to making a shorten frame with the square trigger guard to fit the SUB COMPACT ?

    Some shooters are putting their Sub Compact Slides on “ground down” COMPACT frames so they’d have a fuller GRIP.

    I recently bought a Sig P320 compact in 9mm to give to my son after graduating high school. At 30 yards on only my second attempt, I put a hole in a shotgun shell dead center. Mind you, I haven’t shot a pistol in several years, and I have very little experience with pistols overall. I also was stacking shots in the melamine board I shot with this pistol to the point I could see a quarter sized hole open. I am very impressed. This pistol makes me feel like a pro! I can’t wait to try the .357 sig. variant. My son and I love this pistol!

  • Roy Roberts September 5, 2016, 4:53 pm

    I recently just bought the P320 Full Size .40 cal. Today was my first time shooting it and for some reason the slide would lock to rear with like 2 rounds still in the magazine. What can be the cause of this?

  • Gwizzy March 6, 2016, 11:25 pm

    I purchased the SIG P320 9mm Compact as my very first pistol. I did a lot of research, and tried some friends guns in the past and knew I wanted to go with a SIG. I was a little nervous about the lack of an external safety, but after shooting over 300 rounds, without a single jam or issue, I realized the trigger won’t just pull on its own. The medium grip fits like a glove in my hand and while I still need to practice, I was able to put a few good groups together. The modular design makes cleaning a snap. I am very happy with it so far, and I look forward to years of use.

  • Mark March 31, 2015, 10:01 pm

    I went to the range and fire the Walther ppq, mp9, glock, and this gun. I left with this gun, and I bought full size. I have larger hands, and like the weight and feel of the grip. It was very accurate – I would have taken this first, then the mp9, but I liked the Walther except for grip size. Despite many friends recommendations – I did not have the same comfort and enjoyment with the glock. Just my opinion. We all have different preferences. I do love this gun though.

    Quality really went down hill when Sig manufacture was moved from Germany to Jethro Bodine manufacture in the U.S. Rather than the skilled German workers who get professional training the U.S. has minimum wage people who get little training and work for slave wages.

    The new pistol in question the 320 is just another plasticky unsafe Glock knock off complete with short stroke trigger and no manual safety, in other words an accident waiting to happen. Of course with the almost ZERO mechanical knowledge of the average U.S. gun owner this is not a draw back in sales. The weapon even lacks a Glock trigger safety, although I admit this might be a plus as it might wake up the P320 owner as to the fact that if the trigger is snagged the gun will immediately fire off. Many Glock owners erroneously believe that the ridiculous safety in the Glock trigger will keep the gun from going off at the most inopportune times. Just remember when carrying a gun with no manual safety and a short stroke trigger a hard shell plasticky or hard leather holster is a must and when the gun is removed from said holster its mandatory you unload the weapon immediately and never lay it down loaded out of the holster or else you risk a very serious accident. Of course all this is beyond the comprehension of Jethro until he gets his first and sometimes last accidental discharge from a weapon of this design.

      You couldn’t be a bigger dick if you tried. Thanks for your ‘insight’ into my country and fellow countrymen, “Petru”. Your analysis of our intellect, mechanical acumen, and workplace deficiencies are duly noted. And coming from someone who undoubtedly came from an underdeveloped 3rd world pisspot, it really means something. We could certainly learn a lot from ‘superior’ people like you. Maybe we’ll even use your native country as blueprint for how we can improve our sad living standards. Cheers from someone who lives in a country that matters.

        Well said, Justin. When I feel the need for added safety – I simply don’t rack a round into firing chamber. I love this gun – carry the 320 9mm sc for my carry weapon. BTW – as a new gun owner safety is my first concern at all times. I continue to read insightful articles about my gun such as this article which was both informative and thoroughly enjoyable.

      I agree with petru sova… S&W M&P handguns for me with the optional external safety on all of them. I’ve never shot my foot or leg, even with a million draws from a Serpa holster, some of them with my finger incorrectly bent to unlatch the Serpa and curling on the trigger so that I lifted the handgun from the holster with my trigger on the finger… oops. Glocks go BANG! When this happens as will the P320. My Smith’s go bang only after I flick off the safety with my thumb as I present them. I am especially comfortable drawing from concealed appendix carry with my external safety as I treasure my family jewels.
      Not having an external safety is like riding a motorcycle without a helmet… it’s much cooler until something bad happens and then you wish you had a helmet on, or in this case, an external safety engaged. But what do I know? I’m just a Georgia redneck whose ancestors fought and died in the Civil War Between the States. You can call me Jethro if you like, but even I know the value of an external safety and the risk of not having one.
      If you disagree, go shoot your foot off.

      I agree with Justin, you are a dick. You know little about Sig, the USA or guns for that matter. Ordinarily I don’t shed my opinion based on the comments of a wannabe commando like yourself but this time I must. When 20 top gun enthusiasts, made up of law enforcement personnel, weapons experts and military personnel review and provide a comprehensive and outstanding endorsement of the product, I tend to listen. This makes you look like the foolish ass you’ve already hinted yourself to be by virtue of opening up your Putin mouth. With no axes to grind folks, these are the experts and their review is UNPAID. Theres no monetary gain. I love my P320, chose compact in 9 mm, medium frame. Love that larger mags are compatible, too. (Just can’t put the smaller mags in the larger gun.) Not to mention the no trigger pull for / 3 step or less take down. So…I’m lucky to have found my P 320, and VERY glad the military has chosen it as well!

    Just wondering about the recoil. I have developed what I believe is carpal-tunnel in my right hand and wrist. My son-in-law has 2 rugger 9mm, one with I believe is a 4-4.5 inch barrel and a cc with either a 2.5 or 3 inch barrel. The full size doesn’t bother me nearly as much as the cc. Speaking to a gun dealer the other day and he suggested a Glock Gen 6 because they have added, if I remember right, an additional recoil spring to deal with this problem since many more women were now shooting. Any suggestion on either a full size or I would prefer a cc to help me with this issue? I would like at least a 380.

  • Allen Miller February 16, 2015, 9:31 pm

    It looks like Sig is on a new venture here trying to capture some of Glock’s stronghold on polymer striker pistols. I have several sigs and a glock. The sig 220 and varients are dependable but all have excess muzzle flip due to the high barrel axis. I too have issues with Sigs customer service. My sig 1911 had issues with the slide stop engaging before the magazine was empty and FTE. Sig customer service informed me,”we’ve never heard of that but you can send it in for evaluation”. I did and got it right back with no trouble found. Any reputable 1911 manufacturer knows about these problems and the solutions. A local gunsmith fixed it and informed me these are common 1911 issues. Increasing spring tension on the extractor and plunger springs solved the issues. Sig needs to look into its customer service department.

  • Russ Thomas February 16, 2015, 6:35 pm

    I have been shooting handguns for 54 years, as a LEO, Combat Competitor and Firearms Instructor. I have never been a fan of any pistol that requires a double action trigger finger placement on the first shot, and a single action placement for the subsequent shots. I won’t argue, that close quarter combat, MOA accuracy isn’t necessary, but at any distance beyond 7 yards MAXIMUM, either single (e.g. 1911) or double action only, requires the right hand fit on the grip, maintained constantly, and the right trigger finger placement constantly. I subscribe to the KISS principle; Keep It Short (and) simple. Target shooting is totally different from self-defense shooting, as in the latter the least mechanical movements are best, for muscle memory. Statistics absolutely tell us that self-defense situations where good guys come out winners, requires more than “one shot” and therefore keep it simple! Get a good grip on the draw, with proper hand fit, maintain that good grip, and only the trigger finger in the same placement moves while the grip remains constant throughout the firing sequence.

    I purchased the P320 in the 357 Sig caliber and was pleasantly surprised with it. I actually had to order it through Fin Feather without even holding it. I will definitely be using this as my carry gun.

    • Nic February 17, 2015, 12:13 am

      I carried a S&W 411 in .40 S&W for over 20 years with my CCW, and then switched to the Springfield Armory .40 S&W XD-M for another 9 years. The exposed hammer on the dbl/sgl action 411 scared me one-too-many times and the striker-firing, multiple external safeties, loaded chamber indicator and “cocked” indicator of the XD-M gives me a great feeling of security and control. The full size 4.5 ” barrel of the XD-M offers great accuracy but tends to peek easily from concealment under clothing on appendix or hip carry, so I ordered and now am carrying the Sig P320 Compact in .40 S&W. Like the XD-M, it is striker-fired, has a great trigger (full travel reset only though), some of the same features, better feeling grip control and despite having a shorter barrel (3.9 “) it has as good or better accuracy – even at 25 yards. The shorter barrel solved the peeking problem, too.

    I would imagine this gun is good quality. If Sig could do something about its poor customer service, they might have something here. I’ve called Sig a number of times and get the feeling I’m talking to kids that just got out of high school. I had several 1911 issues that I ended up solving myself. Sig was no help at all.

      I would normally agree- at least per my past experiences – but things must be changing for the better at Sig. I recently bought a Sig Romeo 4 optic and was surprised it did not come with flip up caps. I called Sig to inquire, they were nice and just mailed me out a set at no cost even though the model I bought technically did not come with them. their literature was vague – they could have been dicks but they instead just did something nice and sent me the caps. And you know the Romeo4 is actually quite a nice rd dot.

    • Cody Ryals July 16, 2016, 3:07 pm

      The Texas State Troopers carry the P320 as their duty pistol.

  • Russ February 16, 2015, 1:09 pm

    Real nice gun.
    My Walther PPQ M-1 is better.

  • James Carter February 16, 2015, 1:07 pm

    I happen to own a Sig 229 Elite in 9mm which I like very well. But it does not feel as good when shooting Zombies, house flies and mosquitoes, as my Colt 357 Python, which I bought a long time ago, brand new for $550.00. Didn’t say I ever hit anything, lol

  • Steve Kendell February 16, 2015, 12:20 pm

    I have owned the 9mm FS version for about 5 months and have about 1500 rounds through it. The trigger is very smooth, much nicer than either my Glock 17 or M&P, plus I don’t have to spend good money to make it work. The grip feels good in my hand, not blocky like some others. The night sights are a nice feature, but I would have bought the 320 anyway, as I have replaced the sights with a fiber optic front and a plain rear for competing in USPSA. As for the mag release, it is easy enough to use without modification. However, I believe ambidextrous and reversible are not the same thing. The mag release is reversible just not ambidextrous like the SA XD line. I would like to see the conversion kit for a FS or Carry in .45 acp. that would be sweet!

    Another thorough article , with good info on makeup, and shooting characteristics. Much appreciated!

  • BulletLatin6 February 16, 2015, 11:46 am

    I had the opportunity to put about 200 rounds of 9mm through a P320 a few days ago. Well engineering and made, the pistol reeks quality and innovation in design and configuration flexibility. The trigger bar-sear-striker block mechanisms look like parts from a fine watch and the camming action that activates and releases the striker is a mechanical marvel. However, I’m put off by the barrel-heavy feel and the unnecessary snappiness of the recoil. The takedown lever rubbed the inside of my left thumb to the point of discomfort. The pistol is way more snappy than some other 9mm striker-fired pistols, probably because the bore axis is a little higher, more like the XDm, which is also quite snappy.

    I have been shooting firearms for around 40 years.The semi-automatic pistol handguns that I originally started shooting were either da/sa or double action only no striker fired system available until the Glock striker fire handgun was introduced in the can honestly say after firing hundreds of thousands rounds of ammo that for me as a shooter that I shoot the striker fire system better than all of them. I will not say that I don’t shoot da/sa very well, as I really do especially when on the da/sa I shoot the first shot with the hammer back.I have never shot as well with a double action only type trigger system of any type and that includes a revolver as well.I recently purchased the Sig Sauer P320 and I Love this pistol It will do all that I need it to do. I shoot this pistol better than all that I ever shot, I will say, however,that I have shot the H&K VP9,the FNS-9,the newest Walther PPQ and the M&P Smith & Wesson they are all striker fire and they all preform equally as well for me as the P320.With all the success of the Glock striker fire system it is good to see these other major firearm companies are taking the same path for all of the firearm enthusiast in the world.Well done engineers of the firearm makers. CHEERS

    I recently bought the P320C (medium compact) in 9MM FDE and have maybe 200 rds through it to date…yes, one has to adjust ones grip in order toi avoid putting ANY downward pressure on it while shooting. My big mits consistently did this…I have adjusted my trigger-hand thumb to rest over my support thumb and all is well.
    A VERY nice shooting gun…it will become my primary carry piece.

  • Rob February 16, 2015, 9:43 am

    I don’t think Glock is worried at all. Sig really could have had something with the 320 had they redesigned the grip instead of going with the generic 250 as a base. Now they have a great idea with the same exaggerated bore height of their old model. I have no doubt the trigger system beats the old 229 my department carries but as an overall package I don’t see it as a better system than Glock or M&p or the XDM.

  • Charles Bailey February 16, 2015, 9:20 am

    I carried an H&K P7M8 for years and it would eat anything I tried to feed it and that was the reason I carried it. But it was striker fired and had the worst trigger in the world, but 9MM is available world wide. I found Sig and have stayed away from striker fired ever since.

    • Pops February 16, 2015, 1:03 pm

      No I think the HK VP70z has the worst trigger. But I’ll keep mine, lol. I was about to jump on HK’s new striker pistol, maybe I better check out this Sig first.

  • jason February 16, 2015, 9:03 am

    I have this gun in 9mm and I love it! It is a great investment for the guy that loves to shoot. I picked mine up used but in new condition plus two extra mags which are a little on the high side for me. But the mags are steel and great quality. The night sites are great and good during the day for me. This is not my ccw but if I had the compact it might be. The going price for this gun in Alabama is around 569.00 which is a better deal then a glock 17 gen 4 which runs around 529.00. plus the sig comes with night sights.

  • Mike Hargreaves February 16, 2015, 8:16 am

    A great article! Coming with night sights! Fantastic, I can not understand Glock not doing that with all their pistols, the cost to the company produced steel night sights, should be around $5.00? Add ten dollars to the price, done.

    My Glock 19s have TruGlo fiber optic sights, no way would I not have these on any pistol I own.

    Two inch groups of five rounds at 25 yd’s? Great accuracy. Some intelligent designers involved here! The chopped steel of the port? Nothing is going to stick in the ejection process!

    I am not changing from my Glock 19 anytime soon, it has become a part of me, but depending on the price, that is an awesome pistol. The Secret Service will most likely be the first on the Customer list?

  • Ken February 16, 2015, 8:02 am

    I work at a gun store and have had the pleasure of playing with the same exact gun mentioned in the article. Glock had better do something to step up their game as this Sig P320 is going to take over the striker fired market!

    • Tom February 16, 2015, 10:53 am

      That was exactly my thought – not even a comparison.

      • Jon February 26, 2015, 1:39 pm

        With the horrible quality SIG has been shipping out, Glock and other gun makers have no fear of SIG.

        Horrible products like their 22lr pistol (made by a real crummy subcontractor) that shoots 6 inch groups from a Ransom rest at 7 yards, continue to be sold with the parent company’s blessings even though they know it is a sub-standard product bearing the SIG name.

        With the layoffs at SIG, do you realize things there are in big trouble?

        The continued decline in sales play a big part in things falling apart even with all of the SIG hype.

        • BlueDog09 March 4, 2015, 8:56 am

          Yeah, and Glock is so high quality these days. Their .40 pistols won’t function reliably with lights attached and the Gen4s have a huge issue with ejection patterns. My local PDs have been pulling away from Glock in droves.

          The P320 is a high quality piece for a price that is actually cheaper than the officer price for a glock with std. sights. P320s with night sights are still about $30 more expensive than the Glock officer price with glock night sights. But I’ve found the quality is much higher.

          Glock has a lot to fear b/c if they keep losing LE depts to never ending issues with their Gen4s, companies like Sig and S&W will pick them up quickly. And now their pricing is VERY competitive with Glock. I’ve seen a few local PDs adopt the P320.

  • John W. Hawkins February 16, 2015, 7:40 am

    You gave everything but the price!

    • Landon February 16, 2015, 10:35 am

      I have seen them for 499

    • Ken Carwile February 21, 2015, 11:30 am

      I walked out the door with one for $528. I also asked 2 FFL people about shipping to the door with no 4473 check and they both said no way. They are both people I know so I’m sure it isn’t BS

      • Jim March 22, 2015, 5:05 am

        The shipping to his door is for the x-change kits. The polymer frame slide and barrel can all be purchased on sigs website you just pop in your serialized part that you passed a background check for at the gun store when you bought the original pistol. The trigger assembly is considered the firearm not the whole pistol. The trigger assembly pops right out and will fit in any size p320 you want or caliber.

  • Bob Goodheart February 16, 2015, 5:42 am

    I shot the sig older 300 and i rented at a shooting range in Colorado when i lived there and it was 9mm and it
    did bull eye every shot i was very impressed must of the krut hand guns are good but sig has on them all i guess the 320 is nice and it cheaper too they have a hit on there hands i like the browning high power mark 111 as it is a another fine gun from
    Fn .

  • Mike Washburn February 16, 2015, 4:12 am

    Since I only have one Sig, a P226 which is fantastic, I would be very interested in a P320 except that I an not to pick up another Sig until they recall, or otherwise remediate, those lousy Mosquitos.

    • jay February 16, 2015, 8:58 am

      Sig doesnt make the Mosquito, that is a Umarex creation. In the number of ways that count, the Mosquito specifically is not a Sig Sauer.

      • Jon February 26, 2015, 1:47 pm

        Yet, Sig claims it by having their name boldly placed on it. Regardless of who makes it, when a company places its name on it, they claim it and own any goid and BAD the product produces. Any excuses just don’t cut it when SIG placed their name and Logo on it.

  • Jay February 13, 2015, 5:10 pm

    Splendid pistol. Every bit the the peer of the other ‘new hotness’ striker fire pistol “belle of the ball”.
