The Glock 43x is among the compact, Slimline frames made by Glock. With a 10 round magazine, the Glock 43x is legal for sale in most municipalities. The Slimline frame is ideal for concealed carry, and the subcompact slide of the 43x makes this the most comfortable daily carry with plenty of firepower.
With the enhancements of the Gen5 frames incorporated into the G43x -- short trigger distance, built-in beavertail, reversible magazine catch, a Glock Marksman Barrel (GMB), and front slide serrations. The MOS line has a cut slide plate that is removeable, in order to mount optics onto the slide, such as the Trijicon RMRcc.
