The Glock 43x is a hybrid between the newly released Glock 48 and the smallest 9mm pistol offered by Glock, the Glock 43. Th G43X, along with the G48, is one of Glock’s new “slimline” pistols designed for concealed carry. This appears to be Glock’s attempt to increase the capacity of the G43 while not fundamentally changing the conceal-ability of the Glock 43. We spent some time shooting the G43X at SHOT Show and we really like it!

What is the Glock 43X?


Gun University Glock-43x small imageGlock 43x Gun University Front

Yes, an averaged-sized male could conceal a Glock 19 (the mid-size Glock 9mm and the most popular model they offer), but it was even easier to carry and conceal something a bit smaller and lighter.

Glock 43x Gun University BackGlock finally got the message and came out with teeny-tiny Glock pistols… first the Glock 42 in 380 ACP (which drove people crazy but they still bought it for a year) and then (finally) the Glock 43 in 9mm.

I knew enough to wait for the Glock 43 and I’m glad I did. I thought that it was the best possible CCW gun for me – Glock reliability, decent 9mm capacity, and competent “shootability.”

In fact, it was my CCW choice for a couple of years until the Sig P365 was announced at the 2018 SHOT Show.

For many, the Sig P365 was a superior choice because it was effectively the same size as the Glock 43 but it had DOUBLE the capacity.

The Glock 43 held 6+1 rounds of 9mm while the P365 could hold 12+1.

It took Glock a while to catch-up and it appears that this G43x is their attempt. The G43X holds 10+1 round of 9mm in a slighter larger package.

The “X” in G43X stands for the gun being a cross between the Glock 43 and the new Glock 48. There’s only one other “X” Glock model (so far) and it is a cross between the Glock 19 and the Glock 17.

So what is the Glock 43x?

The Glock 43x is effectively a Glock 43 with a slightly wider and taller frame to increase the grip size and capacity from 6 rounds to 10 rounds of 9mm.

It is one of Glock’s two slim-line pistols introduced at the 2019 SHOT Show.

The Glock 43X is intended to be a concealed carry gun.

The Glock 43x is an interesting move. On one hand, the news has hit the industry with a bit of a thud. A “new” Glock that is bigger than the Glock 43 (and the P365), but still less capacity than the p365. On the other hand, kudos to Glock! They are one of the rare manufacturers who are actually listening to their customers. Let me try to make sense of this… People (me included) have been begging Glock to come out with a slimmer mid/full-size 9mm pistol for years now. Glock listened and here it is. That’s actually pretty awesome. So why the collective…meh? Perhaps it’s unfair.  After all, this pistol is going to be reliable and accurate… it’s a Glock. Let’s dive into our experience with it…

Glock 43X Review: Our Take

We enjoyed shooting this little baby-Glock at the 2019 SHOT Show. I’ll be honest, my “meh” turned into a “oh, I get it” after I held it and send some rounds downrange. Why did I like the G43X? One big reason and a couple smaller ones: The Grip of the G43X is Just Right The G43x’s grip is the goldilocks of the two previous options for a 9mm Glock, the slightly too small to effectively handle (for me) and the slightly too big to comfortable to carry concealed Glock 19. One of the reasons I migrated from the earlier Glock 43 to the Sig P365 was that I could competently shoot the P365. The Glock was just a bit too tiny for my hands. Yes, I could shoot it, but it was difficult to truly “run the gun” through drills. I carried the G43 knowing that it was better than nothing and I liked the concealability. This G43X is still small enough for me to easily conceal while being just the right size in my hands to effectively control and shoot.

Front Cocking/Slide Serrations Glock-43x-Slide-serrations Gun UniversityGlock FamiliarityThere’s something to be said for familiarity. When you pick up the Glock 43x, it feels like a…well…Glock. For some, that’s a bad thing but for others, like me, who are used to Glocks, it’s a welcome feature. I’ve shot THOUSANDS of rounds through Glocks. All that practice/training is not lost when I pick up the G43X. The controls are where I expect them, the grip angle is familiar, and the trigger is predictable with a strong reset. Accuracy This baby can shoot! I’ll get some pictures of the group sizes soon, but i was very happy with the accuracy. I am not a good “group shooter,” especially with Glocks, but I can run them at full speed well-enough.


I don’t know if it was the larger grip, the nice Ameriglo Sights (see our commentary on them below), or just the subcompact slide (yes, subcompact guns are often more accurate because of their tight barrel/slide lock up and spring tension….go figure). I won’t win any bulls-eye competitions with it but it is clearly capable enough to put rounds where you want them. Glock 43x Gun University Ryan ClecknerSig’s P365.


By only having a 10+ round capacity in a larger handgun is was a bit of a missed shot to try to one-up the handgun that one-upped them last year. FINAL TAKE:This Glock 43x is clearly a very competent CCW option. If you’re looking for a new concealed carry gun and you’re a fan of Glock… this may be it!

Glock 43X Top Upgrades & Accessories

Our favorite sights for Glocks are the Trijicon HD™ Tritium sights and the AmeriGlo Agent Nights sights. In our experience, your eye really jumps straight towards the big/colorful front sights. Of course, there are many other sight options available (many of them less expensive than our favorites) for your Glock 43x.  Brownells has 173 different Glock sight options available and Palmetto State Armory has 28 different sets available.
Tool Gun UniversityIf you’re going to change the sights yourself, do yourself a favor and get yourself a Glock front sight tool. The front sight tool we recommend has a large handle to make changing the Glock’s sights easy. There are others available for $2-3 cheaper, but the small extra cost to make the tool easier to use is well worth it for us!

Glock 43x HOLSTER

We’ve found quite a few folks online speculating that the Glock 43x will fit into a Glock 43 holster because they have the same slide. Sure, this makes sense, but the G43X has a slight wider grip that may interfere with the top of some holsters. We doubt it’ll be an issue for many open-top leather holsters but it could be a problem for Kydex holsters. Once we get some in, we’ll test fit them for you and let you know! In the meantime, the following manufacturers are advertising holsters for the Glock 43X: DeSantis Holsters Crossbreed Holsters Galco Holsters
