Glock 43X MOS Review: Still A Top Concealed Carry Contender?
When it comes to choosing a concealed carry pistol, the decision is not easy, nor should it be.
You need to consider everything from the caliber to capacity to ergonomics and more. For many, the Glock 19 checks many boxes, and it does for me, too. However, with the warmer weather approaching, it’s about that time to switch over to something a little more concealable.
I can’t stress enough the importance of a quality holster.
I’ve honestly avoided the Glock 43X MOS due to its capacity, but at the end of the day, Glock’s reliability is something that keeps pulling me back to considering one. So, I gave in and picked one up.
Now that I’ve had it for a few months, I figure it’s time for a review!
Features
Glocks, in general, are not the most feature-packed or fanciest pistols, and the G43X MOS is no exception. However, it still has its much-appreciated quality features!
Modular Optic System (MOS)
Every pistol should come from the factory with an optics-ready slide. Thankfully, this pistol does, and features Glock’s Modular Optic System (MOS).
It’s cut with an RMSc footprint, so you’ll be able to mount plenty of your micro-optics either directly to the slide or with the use of an optic plate. As you can see, even if you don’t mount one right away, the included optic cover plate keeps the slide looking nice and finished.
If only those sights were better.
Glock Marksman Barrel (GMB)
The barrel is something most people don’t pay much attention to, but it is one of the stars of the show. For improved accuracy, the G43X MOS (like other Gen5 pistols) comes standard with the Glock Marksman Barrel, which features enhanced barrel rifling based on the polygonal barrel design. Additionally, it features a target-style crown and tighter chamber specs.
While it won’t turn you from a beginner into a professional shooter, I happily welcome any help I can get in the accuracy department!
Accessory Rail
Unlike the G43 or G43X, the G43X MOS has an accessory rail, which any gun that will potentially fill a defensive role should have.
It’s looking a bit naked without a light mounted.
However, given the small size of the rail and gun overall, you are limited with light options. By far, the most popular light you’ll see paired with the G43X MOS is the Streamlight TLR-7 sub, which I’ll likely be adding soon.
Even if you don’t plan to add a light right away, having the ability to do so is always best.
Range Time
Before obtaining this particular G43X MOS, I had limited experience with them. I had maybe put 200 rounds through one and ultimately didn’t love it or hate it. That said, all of those rounds went down range without a hiccup.
The Strike mag extension adds just the right amount of length to the grip.
Reliability
I’ve now put 300 rounds through this new G43X MOS, again without a single malfunction. I’ve only used the 10-round factory magazines it came with and one factory mag outfitted with a Strike mag extension, but I’ve run a wide variety of ammunition through them. Most of my ammo consisted of 124-grain Blazer Brass FMJs and 115-grain Winchester FMJs, but I also sprinkled in some 115-grain Hornady Critical Defense FTXs.
As expected, the Glock 43X MOS had no issues with any ammo.
Accuracy
Given the primary role of my G43X MOS being concealed carry, I’ve kept all of my shooting within 25 yards. The majority have even been within 15 yards, and within those distances, it’s easy to keep tight groupings. I definitely wouldn’t win any shooting competitions with it, but for defensive purposes, it’s good to go.
First ten rounds through the gun at 10 yards. Had to get used to the slimmer grip!

Pros & Cons
Pros:
- Extremely reliable
- Easily concealable
- Optics-ready slide
- Glock Marksman Barrel
- Vast aftermarket support
Cons:
- Capacity lacks compared to the competition
- RMSc footprint limits your direct-mounting optic choices
Accessories to Consider
Although I’ve been shooting mine without an optic for now, I will add one. Since the slide is cut with an RMSc footprint, it does limit you quite a bit if you don’t want to use an optic plate. If you want a direct-mounting optic, the Vortex Defender CCW is a decent choice, and if you’re not opposed to using an optic plate, check out the Holosun EPS Carry.

MultiCam Black for the win.
Of course, you’ll also need a quality holster if you plan to carry yours. Whether you go with an IWB or OWB holster, make sure it has adequate retention and is comfortable in whatever position you prefer. When a holster isn’t comfortable, you’re much less likely to carry it. I’ve been using an “Aren Elite” AIWB holster from Hilliker Holster and have found it to be great for my needs.
Tyrant’s magwell fits like a glove.
I’ve also been trying out Tyrant CNC’s magwell to get a better grip on the gun when drawing, and it seems to help, although only slightly. It does, however, make your reloads smoother as it helps guide the magazine in.
At least it’s double-digit capacity, although five more rounds would be appreciated.
Lastly, many people pick up a few Shield Arms S15 magazines to increase their capacity. I prefer to stick with OEM magazines, but I have heard great things about the S15s.

Final Thoughts
At the end of the day, it’s hard for anyone to argue against the Glock 43X MOS being a great contender for concealed carry. Does it have room for improvement? You bet, but it is reliable and ready to go out of the box without tweaking or adjustments.
Even larger hands can obtain a solid grip.
If your expectations are set correctly, I think you’ll agree. Carrying a spare magazine will remedy the capacity compliant, and pairing it with a quality optic and light delivers a highly capable carry setup.
Given its small size, I suggest you shoot one for yourself before “pulling the trigger” on purchasing one. If you shoot it comfortably and well, you may just have your next concealed carry gun.
As always, stay safe, train hard, and have fun!
