Glock 43 Vs 43X

Specification Comparison and Reviews

The Glock 43 is a subcompact, 9mm pistol designed for concealed carry. It was the most concealable full-size 9mm on the market, but with its introduction of the G43X, Glock now has a more powerful option with a long barrel and added grip length. Let’s compare these two pistols side by side, to see how Glock 43 vs 43X stack up.

Table of Contents

The Glock 43X is slightly larger than its predecessor, but it still has a slim design which makes the pistol easy to handle. The grip surface on the frame of this pistol has been reshaped with an improved texture which provides better friction between your hand and the firearm. This added grip length allows for more powerful shots with less recoil, which also means a more accurate shot.  

Features of Glock 43 Vs 43X

The G43X is so concealable that it can easily be hidden in a pant or shirt pocket. The standard magazine for this pistol holds 6 rounds of 9mm ammunition, while extended magazines hold up to 10 rounds. 

Grip and Design

The G43X has a longer grip than the original G43. The barrel of this pistol is slightly longer, but not enough to affect concealability or overall size. The slide of this firearm locks back after firing the last round. The G43X has similar dimensions and weight to its predecessor and is compatible with all standard G43 9mm magazines.

Shooting and Aesthetics

The Glock 43 is a bit larger than the G43X. It feels a little top-heavy because of the extra inch of barrel and slide. But the size difference between these two guns is not really big. The weight also varies by less than 10 grams. Since the grips are stippled in both models, this makes grip retention nearly equal. Glock 43X comes with factory night sights while the G43 has none. However, one can purchase aftermarket white dot sight sets for the Glock 43 without having to get an expensive upgrade package. The GLOCK Marksman Barrel (GMB) in G43X does give it a slight advantage over the standard 6 groove single-right-hand twist rifling of the G43. One disadvantage with the Glock 43X is that it would not take standard GLOCK sights without an expensive upgrade package.


So, shooters who are used to aftermarket sight will have to purchase an upgrade package for their guns. Also, because of its slightly longer barrel and slide, the G43X has a slightly higher sight radius. However, the Glock 43 has a trapezoidal sight cut which allows for cheap and easy aftermarket sight installation. Muzzle flip is also more pronounced in G43X due to that extra inch of barrel. So practice time will be needed to get used to it. It is easier to conceal G43 than G43X. See our article on Glock 43 concealed carry holster for more information. As mentioned above, the best use for each of these pistols is different and based on personal preferences. So shooters should weigh out their own advantages and disadvantages to decide which one they should get.

Trigger and Sights

The G43X has a familiar trigger pull which is effective but not too light. The trigger pull for this firearm is 5 pounds, with a small amount of take-up and a short reset. This pistol comes with white three-dot steel sights which are drift adjustable for windage. The rear sight has two dots while the front sight only contains one dot. The G43X is slightly larger but still maintains the minimal profile of its predecessor.

The grip of this firearm has more surface area, which allows for an improved trigger pull with less recoil. These additional features make the G43X ideal for concealed carry and home defense situations. This firearm’s slide does not lock open after firing the last round. This way, a user with the last round in the magazine can quickly reload the last round in the magazine with no need for manually releasing the slide.

After Market Aesthetics

As far as handguns go, the Glock 43 is probably one of the most popular on the market at this point.  Its initial design purpose was to be a concealed carry piece that would fit into the front pocket (or more accurately, the front pant holster). As time progressed, there were some changes made to the gun; however, all of them were pretty minor. One of the only major things changed about this gun was its slightly wider frame at the grip area for increased control by the user. The Glock 43, however, is still the popular choice for pocket carry. It is a good weapon for this purpose and if you’re looking to get one of these handguns, look no further than the Glock 43X with its slightly longer grip that makes it perfect for concealed carry purposes.
