Glock | G43X MOS Doomsday 9mm | 3.39″ Barrel

The GLOCK 43X MOS Doomsday is a compact, optics-ready semi-automatic pistol configured for concealed carry and everyday carry across a range of civilian and competitive environments. It ships with two 10-round magazines and a short 3.39-inch barrel for reduced concealed-carry footprint while retaining standard GLOCK ergonomics. The MOS (Modular Optic System) configuration accepts popular micro red-dot footprints; a Trijicon RMR Type 2 (3.25 MOA) is a practical optic option under $1000 that pairs well for fast target acquisition on a short-slide 9mm. Typical applications include concealed carry and range training/target shooting.
