Glock 43X MOS Optics Ready Carry Pistol

The Glock 43X MOS improves on the base model with an integrated optic cut, as well as a forward rail for weapon lights and lasers. This pistol features a slimmer profile than the Glock 19, while retaining the same grip length and a compact 3.4 inch barrel. This makes the pistol easy to hold steady for a wide variety of shooters, while retaining velocity for carry ammunition.

Though the width feels more “subcompact”, the compact-size grip allows the Glock 43X to have 10+1 magazine capacity, and includes a second magazine for backup when carrying. You can also equip the red dot sight of your choice with the RMSc pattern optic cut, plus a standard Glock rail for attaching any weapon light that fits on the compact frame.

The Glock 43X MOS Pistol is chambered in 9MM Luger and features a compact Slimline frame and a black slide with an nDLC finish.

The frame features elements of the Gen5 and Slimline series such as the short trigger distance, a frame with a built-in beavertail, a reversible magazine catch, and the incredibly accurate, match-grade GLOCK Marksman Barrel (GMB) and precision-milled front serrations.
