The G43X MOS is a Slimline, micro-size 9mm built with a black polymer frame and Glock's Safe Action system. Its slide includes both front and rear serrations and a factory MOS optic cut. The slide is marked "AUSTRIA," reflecting its country of origin.
An Aimpoint ACRO red dot is mounted using the included ACRO-to-Glock MOS adapter plate. The enclosed-emitter design shields the emitter from debris, and the dot presentation is a simple, bright red aiming point. Fixed iron sights remain in place.
The 3.41 in Glock Marksman Barrel uses a hexagonal rifling profile and a refined crown. The right-hand twist rate is 1:9.84. The steel barrel and precise crown support consistent alignment with the installed optic.
Ergonomics are straightforward and modern: the grip has a stippled texture with no finger grooves, and controls are set up for striker-fired operation. The Slimline MOS interface is compatible with RMSc-pattern micro optics if the user chooses to change configurations in the future.
Capacity is 15+1 rounds of 9mm Luger, and this pistol includes two steel, double-column 43X-pattern magazines. The configuration offers a ready-to-use optics setup with the ACRO mounted and the MOS plate cover included for flexibility.
