Chambered in 9×19 the G43X MOS features slide cuts designed for specific micro-optics and the GLOCK Slim Mounting Rail for mounting accessories. The perfect tactical partner in the well-known GLOCK Slimline design for comfortable concealability.

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 and the G42, a reversible magazine catch. This model has the incredibly accurate, match-grade GLOCK Marksman Barrel (GMB) of the Gen5 series. The G43X MOS also features precision-milled front serrations.

The slim magazine is built in reliable GLOCK style, it has an orange magazine follower for higher visibility and is specifically developed to ensure the 10 rds magazine capacity.
