Chambered in 9x19 the G43X MOS features slide cuts designed for specific micro-optics and the GLOCK Slim Mounting Rail for mounting accessories.

The G43X MOS has a short subcompact barrel length and a comfortably balanced, versatile compact-size grip with a minimal profile. It incorporates elements of the Slimline series such as the short trigger distance, a frame with a built-in beavertail as seen on the G43- New Window and the G42, a reversible magazine catch.

This model has the incredibly accurate, match-grade GLOCK Marksman Barrel (GMB) of the Gen5 series as well as the tough nDLC finish on the slide. The G43X MOS also features precision-milled front serrations. The slim magazine has an orange magazine follower for higher visibility and is specifically developed to ensure the 10 rds magazine capacity. Note: The G43X with the Modular Optic System (MOS) does not come with adapter plates.
