GLOCK 43X COA: The 9mm subcompact pistol field tested

Only a comparison with a medium-sized hand shows how small the Glock 43X COA is. The Aimpoint red dot sight included in the scope of delivery is not bulky, it just looks that way on this petite gun. 

The GLOCK design, which is over 40 years old, paved the way for the very simple "draw-aim-shoot" concept: no manual safeties, no corners and edges, and a relatively low weight with small size. All this together with an ergonomic grip, which brings great advantages in fast shooting.

The GLOCK 17, designed as a service pistol, quickly had successors, including sub-compact models such as the G26. Just over ten years ago, the Model 43 in 9mm chambering was launched on the market. Marketed in the USA as an "ultra concealable pistol", it has a short, single-stack magazine with a capacity of just six cartridges. However, the grip, which is also very short, is usually only sufficient for three fingers –replacement magazines with an extended, ergonomically shaped base provide some relief. The  COA version of the GLOCK 43X now available is designed for ten cartridges; medium-sized hands will find room for all fingers on the slightly longer grip. In response to the strong demand for carry pistols with a red dot option, this test gun came with a reflex sight from Aimpoint fitted and zeroed. We already presented the pistol – now comes the test.

With a little practice, a GLOCK can be stripped and reassembled in half a minute. Thanks to the very high reliability of GLOCKs, this will hardly ever be necessary outdoors.

The GLOCK 43X COA in detail

When loaded, this pistol weighs only around 650 grams, depending on the cartridge – so it won't pull your trousers down. Functionally there is nothing new either, it remains a GLOCK in all respects. For non-GLOCK connoisseurs: a polymer framed, striker-fired pistol with partially pre-cocked striker. A safety in the center of the trigger eliminates the need for manual safeties. The magazine release can be moved to the right. There are no backstrap adapters for this version, but the grip angle and feel leave nothing to be desired for medium-sized hands. The grip of almost every GLOCK fits average hands perfectly from aiming to firing.

Even though this Picatinny rail of the GLOCK 43X COA only has one groove, it is perfectly adequate for mounting small lights or lasers.
The short barrel of the GLOCK 43X COA doesn't allow for much acceleration! Heavily loaded cartridges, such as the 95-gr Magtech, produce a strong muzzle flash with a dazzling effect in the twilight. Due to insufficient velocity, some hollow-point designs also fail to expand. However, there are some loads with very low muzzle flash that are well suited to short barrels, such as the three cartridge types shown here as examples.

The GLOCK G43X COA on the shooting range

Apart from impressions, there is hardly anything else to report on the proper handling of a GLOCK. Malfunctions have always been rare in tests with GLOCK firearms, and none occurred in this test either. Despite the short barrel, both tight and fast groups could be achieved thanks to the red dot sight. 

The only special considerations for this very short variant concern the ammunition. This is because after the chamber, only about 55 mm of barrel length is available. Loads with high propellant densities can be blinding in low light. It takes time to see if and how the target reacts after firing. The 100-gr S&B XRG, 100-gr Hornady Critical Defence (FTX) Lite and the 108-gr GECO Action Extreme JHP cope well with the short barrel of the GLOCK 43X, both in terms of expansion and muzzle flash. In the end, the Hornady load was also able to claim the accuracy victory with a grouping of 29 mm at 15 meters.

GLOCK 43X COA: conclusions from the test 

The combination of the high-quality red dot sight with the carry gun, which has already become a modern icon, is a unique selling point. The price-performance ratio, including the Aimpoint COA, is also hard to beat. For this, it comes highly recommended.
