Exclusive Details on SIG’s New P365XL and P320 X5 Legion

The new P365 XL and P320 X5 Legion details were released to dealers this week, and promptly leaked to the internet at large.

SIG Sauer released sell sheets to dealers for two new models and some of the details have been leaked early. We’ve got a couple of pictures, but the full announcement will come in a couple of weeks. Basically, the P365 is getting supersized to the P365XL, and the P320 X5 enters the Legion club.

Taller, longer, wider with an extended beavertail, flat trigger, and optic-ready plate, the XL adds 2-rounds for 12+1 capacity.

P365 XL

This new XL model packs an extra two rounds into the grip, which is attractive to many who carry a gun daily, The P365 XL’s longer grip is half an inch taller, going from 4.3″ to 4.8″. This has expanded the capacity from 10+1 to 12+1, and the magazine is still flush-fitting. Plus, there will be 15-round mags available with extension plates!

What’s even cooler is the XL mags are compatible with the original P365. So, you can plug the 12 rounders and 15 rounders into your P365! That 15+1 round capacity on the XL rivals many of the most popular compact carry guns on the market but does so in a smaller package overall. Just as the P365 turned the subcompact market on its head, the XL may very well do the same for the compact class of carry guns.

More about the dimensions. The extra grip size is balanced with a little more length in the slide, too, going from 5.8″ to 6.6″. The new barrel is 3.7″ versus 3.1″ in the original.

They haven’t just stretched the P365 frame. This new XL is also 2mm wider, going from 1.0″ wide to 1.1″ wide. The beavertail is extended for a higher grip, as well. Update: the extra 2mm width is in the flared portion of the mag well; the grip itself isn’t bigger and the new 15-round mags are backward compatible with other P365 pistols.

It’s also got an optics-ready sight plate and XRAY3 day/night sights. Also new is the XSeries flat trigger that breaks at 90 degrees.

It’s still got a stainless steel slide with a Nitron finish and stainless steel frame. It’s got the P365 XSeries polymer grips, and it’s rated for +P 9mm ammo. We expect full specs and pricing in mid-June.

The P320 X5 Legion is ready for the range and ships with all the upgrades you’d pay extra for.

P320 X5 Legion

On the completely opposite end of the carry spectrum is the new full-size P320 X5 Legion. It’s updated and modified for serious range work straight from the factory and buying this Legion series gun also grants you access to the exclusive SIG Legion club.

Starting at the top, you’ll notice the Dawson Precision Fiber optic front sight and adjustable rear sight. Plus, the rear sight plate is compatible with Romeo1 optics and anything else compatible with the M17, and there are many options for the M17.

There are lightening cutouts in the top of the slide to reduce felt recoil which helps you stay on target. The slide is finished with their Legion Gray PVD coating. It’s got a 5″ match grade bull barrel.

While the lightening cuts keep the slide under control, additional control comes with added weight in the grip. SIG used their TXG Tungsten Infused Heavy XGrip Module. Tungsten is much denser than steel and this added weight in the grip puts the center of gravity lower so you can stay on target. It looks like the beavertail is extended as well.

What really separates this pistol from its brethren is its lightened and skeletonized flat trigger that breaks at four pounds! From our secret preview at NRAAM 2019, we can confidently say that this is one of the best triggers SIG has ever released.

Additional features include an accessories rail and enlarged mag well. It ships with three 17-round mags (or 10-round mags for compliance). The magazines are steel with Henning Group aluminum baseplates.

We’ll have more information, pictures, and pricing in a few weeks.

    Is the trigger mechanism interchangeable with the regular 365 ????

  • Rangemaster11B May 25, 2019, 11:19 am

    So, the 365XL is essentially a 320 subcompact, without the option of interchangeability.

    As a P365 owner, I see no purpose for the P365XL. I bought the P365 because it was small, light and concealable. So now they make one with none of those attributes. I bet they will sell like hotcakes in spite of it. Why not just buy a P2022 ?

    • Charles Hutson May 24, 2019, 6:32 pm

      The guy with a bigger hand and wants the same size form factor will love this gun

  • Spencer Odom May 24, 2019, 10:49 am

    Polymer gun and Legion don’t really seem like they go together, but maybe I’m old school. Maybe this 365 will have a better launch.

    • Charles Hutson May 24, 2019, 6:37 pm

      You are confusing the two, The 365 is not a Legion series. The 365x will out sell the regular 365, it is now a man hand size pistol

    new X5 Legion looks incredible. I know what I’m buying this fall.

    A couple of months back I asked SIG if they would make a 365/RX model. My old eyes being the motivation.
    Surprisingly they said it was in the works.
    When I’ve asked questions from other companies they were always evasive and secretive. Big difference in customer relations.
    I will probably get an XL but I could’ve done without the extra slide length. I’ve shot with straight triggers and saw no difference in my performance so I can take it or leave it. As for the grip I’m betting their market research revealed that the majority of 365 owners are carrying with the 12rd mag already so they just made the grip that size.
    The 1mm width increase is probably to accommodate the Romeo Zero sight they are building for it. Just a guess but they probably could only get the thing so small before it wouldn’t take a decent battery. My 2¢.
    I love my 365 and would go so far as to say it’s the best handgun I’ve ever had overall.
    They caught all the other companies flat footed.

    So, SIG made a Taurus G2C out of their pocket mini, lol.

  • Tman May 24, 2019, 8:57 am

    Hopefully they make the XL with a threaded barrel!!
    I would definitely get one and get several of the 15 rounders to swap back and forth with my P365!!

  • Michael May 24, 2019, 8:22 am

    These new Sigs are beautiful! Does anyone know what “version” Sig would be on with the standard 365’S ?? I know it’s probably not an issue anymore with the dragging firing pin and other issues. But that will always be in the back of my mind if it was my carry weapon…
