GLOCK 43X MOS – Compact, Concealable, Optics-Ready

The GLOCK 43X MOS delivers the perfect balance of concealability, comfort, and modern performance features. Combining the slim, subcompact profile of the G43 series with a longer grip for improved control, the 43X MOS is purpose-built for concealed carry while offering the benefits of the Modular Optic System (MOS) for those who want to mount a micro red dot sight.

Its Matte Black nDLC finish and Glock Marksman Barrel (GMB) provide improved accuracy, durability, and corrosion resistance, while front slide serrations make slide manipulation fast and secure. Designed without finger grooves, the grip accommodates a wide range of hand sizes, and the flared magwell speeds up reloads under pressure.
