Glock 19 and 17 Gen 5 Unleashed — Full Review

For those of you who are fans of the combat Tupperware, the wait is over! The Glock Gen 5 has arrived. GA team got their hands on the new Glock 19 and Glock 17 Gen 5. Aside from some cosmetic changes and few functional changes, they function just as we come to expect from Glock — flawlessly.

Updated Ergonomics
Goodbye to the finger grooves. The Gen 5 gets back to the roots of the original. Considering this is one of the first things requested when customizing, it just made sense. The Gen 5 grips look like a Gen 1 and Gen 4 hybrid. It has the texture of the Gen 4 with grip of the Gen 1. Although similar to the Gen 4 models, it comes with the modular backstraps and beavertail that allows users to swap out from two different sizes of backstraps each with or without the beavertail.

A left side slide release makes the Gen 5 models finally fully ambidextrous, as it retains the Gen 4 reversible magazine release. I have only owned one Glock from the pre-finger groove times, so this is relatively new to me. I don’t feel it is a huge difference, but I like the feel of the new model. The coating is a “nDLC” finish on the barrel and slide. According to Glock, this is more durable and tougher than previous finishes. It’s currently exclusive to Gen 5 models.
The magazine well has been flared, which is nice for both tactical and competitive shooters. Looks like Glock caught the fever of the SIG P320X5 on this one, but it is a nice touch. Reloads with the Gen 5’s are a snap. Competitive shooters are going to love this update, and it will pretty much make the purchase of a Gen 5 mandatory. For Production class add on magwells are a no-no. But if your gun happens to come from the factory that way — it’s good to go. The new Glock Gen 5 magazines feature an orange follower and floor plate that is extended in the front for faster mag changes. These mags are also interchangeable with previous models.

Glock 19 and 17 Gen 5 Unleashed — Full ReviewThe biggest upgrade is what Glock calls the new “Marksman barrel.” This change supposedly halves the accuracy of the old Glock standard. Before, the barrels came from the factory with 4 inches at 25 yards as the standard. Now the bar has been raised to 4 inches at 50 yards.

Time will tell if this matters to most shooters, but it is nice to know the possibility is there. When I field tested the guns for accuracy against a Gen 4, the new model did have a slight edge. It also remains to be seen, if Glock will make the new barrels in Gen 3 for all the poor people stuck in Commie-fornia.  An interesting point is the new barrel drops the polygonal rifling in favor of regular rifling.Glock 19 and 17 Gen 5 Unleashed — Full Review

There have been major changes to the geometry of the safety plunger. This is the part that makes the Glock drop safe. It is now angled, which makes for a better trigger pull out of the box. The entire trigger group has changed, meaning your 5-gallon bucket of disconnectors and different springs is now a boat anchor. No doubt the aftermarket will be scrambling to catch up. The Gen 5 is still not a custom-tuned single action, but it is an improvement.Glock 19 and 17 Gen 5 Unleashed — Full Review

The coating on the Gen 5 is a Glock proprietary finish called nDLC. This, we are told, is the toughest wearing finish every applied by Glock. I suppose it will take a few thousand draws from the holster to tell, in my experience the Glock finish was already among the best.Glock 19 and 17 Gen 5 Unleashed — Full ReviewGlock 19 and 17 Gen 5 Unleashed — Full Review

The internals got a bit of a facelift as well, with the return to a two pin rather than 3 pin frame. Glock says the Gen 5 will only be available in 9mm, and much of the old pin design was directly related to the 40 Cal. As a believer in 40 S&W, this is a bit of bad news to me. The takedown lever has been fully redesigned, switching from a leaf spring to a coil spring. The striker has changed, along with the firing pin hole. It is now tear-drop shaped, to allow more tolerance for foreign objects in the firing pin channel. This is supposed to offer a substantial decrease in the odds of a light strike due to grime. We were told that the Gen 5 Glock has set a new record in testing for mean stoppages between rounds at 11,000.Glock 19 and 17 Gen 5 Unleashed — Full Review

The Gen 5 comes with the Glock standard plastics sights, but also now offer Ameriglo tritiums as an option. I used these sights at the Glock Operators Course earlier in the month, and they are a great set up. If you plan on using your Gen 5 as a duty or carry gun, I recommend them highly.

Glock Operators Course

Glock 19 and 17 Gen 5 Unleashed — Full ReviewEarlier in the summer, I had the opportunity to run an abbreviated Glock Operators Course with the new Gen 5. The Glock Operators Course (GOC) teaches you to drive or “operate” a Glock. And at least the chief architect of the course can lay some claim to the word, my friend Joseph Parent. Parent is an old hand from 2nd Force Recon, a former SOTG instructor, and a 3 Division USPSA Master class shooter. Parent can sling a pistol, as can all of his assistant instructors. He has assembled an all star cast of other gunfighters. I really liked that his crew had a mix of U.S. military, police, and SWAT members. No one organization has a monopoly on the best training or ideas. Every one involved in GOC is a consummate professional, bringing years of experience to the venue.  Or in the case of his instructor named “Gen1” four decades.

I hesitate to call the GOC a basic course because no one likes a basic course. The market demands a Level 54 Paladin with ninja stars and SWAT rolls course. A better description would be a course with something for shooters at all levels. It is not for new shooters that is certain. To even get in the door, you must be active Military, Police, an NRA instructor or a Glock Shooting Sports Foundation (GSSF) member.

Glock 19 and 17 Gen 5 Unleashed — Full ReviewMuch like my preferred teaching style, the course begins with a rapid overview of the basics. This is very important. You can’t build a foundation on sand. The overview is designed to offer tweaks to existing skills or identify missing parts. You would be amazed how many experienced shooters have chunk of knowledge missing. Every skill is both explained and demonstrated, then done at speed live fire.

The course involved lots of work from the draw, and we utilized BladeTech holsters. Every skill imaginable with a pistol is covered, from draws to one handed shooting, to shooting on the move. Our course was compressed from two days into one, so the pace was kept high.

There is enough here to challenge anyone, and if you carry a Glock, it is worth checking out.

    I still have my “tinforized” Gen 1 17 with a 3 digit serial number. It sat outside in a toolbox for 7 years and didn’t rust. It got cleaned and works perfectly. These guns just don’t fail to operate and they very rarely break parts. Having been a gunsmith for more than 30 years, I don’t do much to them except change sights. There is no such thing as an accidental discharge, even if the one in question malfunctions when being racked, you know you are making it hot. Keep it pointed in a SAFE direction and it won’t matter. I have had this particular 17 since 1985 and carried it plenty. It NEVER fired without pulling the trigger, not even once, so the safety argument is moot. Learn how to safely handle a firearm and you won’t have “accidents”. I went through Glock’s armourer school, at the time it was the only way to get parts. 32 years later, it is still a great design and a great all around firearm. It currently resides on my nightstand and yes I would bet my life on it.

    Waste of money just another gimmick by Glock to raise revenue – also, justifying their failed attempt at securing the Military contract and the expense of new molds, jigs, and engineering designs in that attempt. Problem with Glock (like always) is they half ass all their so called redesigns because they sell on their prior reputation and fan club.

    • Vanns40 December 18, 2017, 10:00 am

      It’s gets really tiring hearing people trash one gun or the other. Just wondering what gun you shoot, how often you shoot and how many rounds you’ve put through it? I’ve owned, still own and carried 1911’s. Fine guns. I’ve owned and carried multiple Sigs, fine guns, but what I ultimately settled on, decades ago was Glock because it fit me and carrying one up to 18 hrs a day I never had one let me down. And yeah, I do shoot ‘em. More than 200,000 rounds on the 19 & 23, not nearly that much on the 17.

      If they don’t fit you, fine, but they’re great guns and to sit back and run them down….well, I’d like to know what your practical experience is with them, how many tens of thousands of rounds you, personally have put through one and what the first hand basis is for your criticism.

  • Ken December 18, 2017, 8:32 am

    All guns have a “Safety”, it is the person in control of it using the NRA”s three rules for safe handling of a firearm.
    There is no such thing as an accidental discharge with a fire arm.
    Unscheduled firing events happen all too often.
    Stay SAFE !!!!!!

    Sirs: I own a Gen 4 Glock 19 and Gen 3 Glock 34. But, I no longer carry either for protection, due to my lack of faith that I can keep everything away from accidentally firing the trigger. Sooner or later I believe there will be an accidental discharge with this so-called safety system of Glocks\’. I do carry another brand with a trigger/hammer disconnect, manually operated.
    When Glock offers a manual safety or manual disconnect, I will consider them. I note the US military required that Glock put a manual safety of their submitted guns for the new standard military handgun qualification. But, it is not on their commercial guns.
    Than you; Dr. JRB

    • Sedonabear August 29, 2017, 12:51 am

      If you use the term, “accidental discharge” you are betrayed by your ignorance and lack of training. The gun is the “tool set”. Your training is your “skill set”. You have to have both in order to be both safe and effective. At the most basic and practical level of firearms training, you immediately learn that there is almost no such thing as an “accidental discharge”. There is only and almost exclusively “negligent discharge”. If you experience any kind of unintentional discharge you have likely disregarded and broken one or more of the Universal Rules of Firearms Safety. Hire an instructor, then go pick out your Glock to carry in comfort and confidence.

    • Michael Todd August 29, 2017, 6:12 am

      Maybe you need to buy a better holster and practice proper draw techniques. That was without a doubt a rookie comment.

    • Infidel762x51 August 29, 2017, 8:37 am

      The Cominially safety is a reasonable upgrade. The model submitted to the Army for testing had a factory installed safety but Glock decided they would not release that to the public.

    • Gun chick August 30, 2017, 8:00 am

      Definitely agree with everyone else. Accidents happen all the time, but that doesn’t mean it’s the guns fault. There’s only one way a gun is going to go off, and that’s if someone pulls that trigger. keep your finger out of there, unless you need it in a life/death situation, or target shooting.

      • 454jim454 September 22, 2017, 7:08 pm

        I’ve seen 1911’s fail to fire because the manual safety was not disengaged. I’ve seen officers shoot themselves with 1911’s putting back in the holster. I’ve seen stupid things with revolvers too. The gun has no brain, you do. If you are careless or suffer a lack of concentration you become dangerous despite the gun’s safety equipment. It all depends on you, not the gun.

    • Roger October 29, 2017, 5:01 pm

      A Glock could be buried in a mud hole for a year and would still fire when picked up. I just finished a tactical handgun course. Virtually every non Glock experienced a malfunction while the Glocks had none. In addition I understand that if given a choice, Tier 1 operators carry a G19 or G17. 4
      Rule#3: You do not place your finger on your trigger unless you are ready to destroy something. That rule alone eliminates “accidental” discharges.

    • Alex December 18, 2017, 6:41 am

      Lack of faith? More like lack of training and excess of ignorance. The only way wou get an “accidentally discharge ” is when you accidentally pull the trigger. You own two Glock but that does not make you an expert.

    • Tim Lane December 18, 2017, 9:09 am

      Wanna sell yours since you afraid of it. I’ve carried a glock every day for over 20 years without an AD. I ain’t scared.

    • RI Redneck December 18, 2017, 6:26 pm

      As the saying goes, keep your booger hook off the bang switch till you’re ready to fire and you won’t have a problem.

      Then do us all a favor and don’t carry a firearm at all. Apparently your training is missing altogether and on that point you are correct: you are afraid of a negligent discharge for a good reason. You have never been trained, or what little training you have had has lapsed by years.

  • Bobo August 28, 2017, 11:08 am

    Yawn. There isn’t enough here for me to trade in my 19/4 for the five. I like the finger grooves. What they could have done was change those crappy sights

  • Bee August 28, 2017, 10:56 am

    The comment about USPSA Production Division legal with the magwell changes (“For Production class add on magwells are a no-no. But if your gun happens to come from the factory that way — it’s good to go. “) is not entirely correct. The current rulebook Appendix D4, Production Division, 22.4 Magwll opening says, “The longitudinal (front-to-back) dimension of the
    opening may be more than 1/4” greater than the corresponding dimension of a magazine. External flaring remains PROHIBITED.” I believe there is an error in the USPSA wording. I suspect what USPSA meant to say is ‘The longitudinal (front-to-back) dimension of the opening may NOT be more than 1/4” greater than the corresponding dimension of a magazine. External flaring remains PROHIBITED.”
    Regardless of the proper wording, I believe Glock did its best to ensure the pistol is compliant with USPSA Production Division rules.

  • Michael Douchette August 28, 2017, 10:48 am

    They’ve made an Austrian FNS. Flared magwell, ambi slide lock, no finger grooves… FN’s had it perfect for years.

    Well, there you go.
    If I didn’t already have Gen 1, 2 and 3 and a bucket of parts, I’d ponder one of these “sooner”, but I’ll give one a whirl one of these days, and probably buy one “later”.

  • Mark Are August 28, 2017, 9:34 am

    I wonder how much longer before the Gen 5 in REAL calibers are released. Especially .45 or 10mm.
