About the Gun

Fifth-generation compact pistol incorporates the Modular Optic System with a factory-milled slide that accepts miniature reflex sights through interchangeable adapter plates without requiring additional machining. It features a polymer frame without finger grooves, interchangeable backstraps for grip customization, a modestly flared magazine well, an ambidextrous slide stop lever, nDLC finish on the slide, front slide serrations, and the Glock Marksman Barrel with hybrid polygonal rifling and a revised crown profile. The overall configuration maintains the established short-recoil, locked-breech operating system with a striker-fired trigger mechanism and standard fixed sights.

Analysis

Introduction of the MOS configuration on the Gen5 platform was in response to increasing interest in pistol-mounted optics among law enforcement and civilian users. The factory-integrated slide cut, combined with front slide serrations from the outset, preserved the pistol’s standard operating characteristics while simplifying optic installation and slide manipulation compared to aftermarket modifications on earlier models. Production volumes were lower than those of the non-MOS variant, resulting in fewer examples reaching the market before the broader shift away from the Gen5 series in late 2025. On the secondary market these optics-ready units have retained stronger demand and value relative to standard counterparts due to the added utility of the sighting interface.
