Glock 43X MOS 9mm 3.4″ Barrel 15-Rounds 2 Mags

The Glock 43X MOS is built around a 3.41-inch Glock Marksman Barrel with nDLC finish, an advanced surface treatment that delivers optimal hardness, exceptional corrosion resistance, and a matte surface that minimizes light reflection in the field and during carry. The precision machined MOS slide accepts miniature red dot sights via separately available adapter plates, giving shooters a factory-ready optic mounting platform with broad compatibility across popular red dot footprints, while the serrated slide provides positive manipulation during press checks and administrative handling in 9mm Luger. For concealed carry owners and competition shooters who want a factory optics-ready sub-compact 9mm with a proven Glock Marksman Barrel and nDLC protected slide, the 43X MOS delivers that complete capability in a slim and refined package.

The Glock 43X MOS polymer frame incorporates a built-in beavertail for improved recoil control and a more comfortable and consistent grip purchase, an accessory rail for lights and lasers, and a no-finger-groove texture that accommodates a wider range of hand sizes and grip styles than grooved alternatives. The extractor serves as a loaded chamber indicator, providing both a visual and tactile reference to confirm whether a cartridge is chambered, and the trigger pull is set at approximately 5.5 pounds for a consistent and deliberate break on every shot. For everyday carry shooters and duty-oriented users who want a slim, optics-ready sub-compact with a beavertail frame, accessory rail, and high-capacity 15-round magazines in a factory-complete package, the Glock 43X MOS is a versatile and capable platform.

The Glock 43X MOS ships as a fully equipped carry package including two 15-round magazines, a mag loader, cleaning kit, pistol case, and gun lock, providing everything needed to get the pistol into service without additional accessory purchases beyond an optic and adapter plate. At 1.06 pounds, 6.50 inches in overall length, 5.04 inches in height, and 1.10 inches in width, the 43X MOS strikes an ideal balance between capacity, concealability, and shootability that larger sub-compact platforms often sacrifice. For shooters seeking a factory-complete, optics-ready, high-capacity sub-compact 9mm with Glock’s proven reliability and a full accessory kit included, the Glock 43X MOS is available at GrabAGun.
