The Glock 43X MOS is built on a black polymer frame with an integrated accessory rail and beavertail, pairing a 3.41-inch GMB steel barrel with a serrated black steel slide featuring an advanced surface treatment for optimal hardness, reduced wear, and corrosion resistance across the slide's service life. The matte surface finish minimizes light reflection in field and tactical conditions, and the extractor serves as a loaded chamber indicator providing both visual and physical confirmation of a chambered round. Three sequential safeties including firing pin and trigger block disengage automatically as the trigger is pulled and re-engage upon trigger release for consistent passive safety performance.
The MOS precision-machined slide provides a direct mounting system for popular miniature red dot sights via separately available adapter plates, giving 43X MOS owners a factory-supported optic mounting solution without aftermarket slide milling. At 1.06 lbs and 1.10 inches wide, the 43X MOS maintains the slim-profile subcompact slide dimensions that define the 43X platform while delivering 15+1 capacity through a compact grip length. Fixed sights provide immediate out-of-box iron sight capability alongside the MOS optic mounting system.
Glock engineered the 43X MOS around the combination of compact grip and subcompact-slim slide geometry that defines the 43X series, adding the MOS optic system to bring factory-supported red dot capability to the slim-profile carry platform. The 43X MOS is compatible with standard Glock component accessories and ships complete with two magazines, mag loader, cleaning kit, pistol case, and gun lock for a ready-to-run out-of-box configuration. Adapter plates for the MOS system are sold separately and are not included with the 43X MOS.
