GLOCK 43X MOS 9mm - Aimpoint COA - 3.39" - 2x 15 Round Magazines - Pistol

The Glock G43X MOS with Aimpoint COA is the factory-optic Slimline package that puts a co-engineered A-CUT mounted Aimpoint COA red dot on the G43X platform — the slim, subcompact-slide/compact-grip combination that made the 43X one of the most popular carry pistols in the US, now shipping with the new factory 15-round Slimline magazine and a factory-installed enclosed red dot ready to run.

The Glock G43X MOS is a striker-fired semi-automatic pistol chambered in 9mm Luger, built on a black Slimline polymer frame with Glock Slim Mounting Rail, black nDLC-finished MOS8 steel slide with front serrations, 3.41-inch Glock Marksman Barrel, and factory-installed Aimpoint COA 3.5 MOA red dot.

The A-CUT interface mounts the Aimpoint COA directly into the slide without adapter plates — keeping the optic lower over the bore for a more natural iron sight index and a mechanically stable connection that resists zero shift under carry and recoil conditions. The Aimpoint COA is a fully enclosed, nitrogen-purged optic with a 3.5 MOA dot, 11 brightness settings including four dedicated night vision levels, NVD compatibility, and anti-reflex coatings on all surfaces. Fixed front and rear white sights co-witness with the COA for a usable iron sight backup. The Slimline frame's built-in beavertail, short trigger distance, and 1.10-inch width are unchanged from the standard G43X, preserving the carry-friendly profile that defines the platform. The Glock Slim Mounting Rail accepts compact lights and lasers. The reversible magazine catch accommodates left-hand use. Three interchangeable backstrap sizes are included. Two 15-round factory Slimline magazines, speed loader, cleaning set, backstrap set, and pistol case are included.
