Glock 43X MOS Features
The Glock 43X MOS combines a compact-size grip length with a subcompact-slim slide and precision-machined MOS optic mounting system, delivering a versatile, optics-ready carry platform compatible with popular miniature red dot sights via separately sold adapter plates. The Glock Marksman Barrel provides enhanced accuracy and reliability, while the nDLC slide finish delivers optimal hardness, corrosion resistance, and a matte surface that minimizes light reflection in the field. Three sequential safeties disengage as the trigger is pulled and automatically re-engage upon release for safe, consistent carry performance.
This subcompact 9mm Luger striker-fired pistol features a polymer frame with integrated accessory rail, beavertail, no finger grooves for adaptable grip fit, and an extractor that serves as a loaded chamber indicator for visual and tactile chamber status confirmation. The included Aimpoint COA 3.5 MOA red dot gives shooters a factory-installed optic solution right out of the box for fast, accurate target acquisition. At just 1.06 lbs with a 6.50" OAL and 1.10" width, the 43X MOS is one of the slimmest and most capable optic-ready 15-round subcompact carry pistols available.
Glock has set the standard for reliable, lightweight polymer-frame pistols for decades, and the 43X MOS continues that tradition with a purpose-built optics-ready slim carry platform that balances capacity, concealability, and modern optic compatibility. The combination of MOS slide, Aimpoint COA red dot, and 15+1 capacity makes the 43X MOS one of the more complete and well-appointed subcompact carry packages on the market. It stands as a compelling choice for everyday carry shooters who want a factory optic-ready setup without additional gunsmith work.
