The Glock 43X MOS is a slimline, 9mm subcompact pistol designed for concealed carry. It features an optics-ready slide for micro red-dot sights and an integrated accessory rail for tactical lights. Delivering a 10+1 capacity, it blends a compact grip with a short barrel for comfortable everyday carry. The slide is precision-milled to easily mount popular micro-optics. (Note: Some newer models feature a revised RMSc footprint, which allows direct mounting for optics like the Holosun EPS Carry without needing adapter plates). Includes the incredibly accurate Match-Grade Glock Marksman Barrel (GMB), front slide serrations, and an ambidextrous reversible magazine catch.
