Glock G45/MOS 9mm Pistol, Black – PA455S203MOS

The GLOCK 45 MOS is a compact crossover 9x19mm pistol that merges a compact slide with a full-size frame, delivering all the advancements of the Gen5 series. Its MOS (Modular Optic System) configuration allows for effortless mounting of a miniature reflex sight directly onto the slide—no additional slide cuts or mounting systems required. Built from the foundation of the military-proven G19X and tailored to meet the rigorous demands of operators and global law enforcement, the G45 MOS stands as a purpose-built duty pistol.

The slide features GLOCK’s durable, non-reflective black nDLC finish and front serrations for enhanced grip during slide manipulation, even in wet conditions. The black polymer frame includes a flared magwell for quick reloads, aggressive grip texture for secure handling, and GLOCK’s Modular Backstrap System for personalized ergonomics. Rounding out its feature set are a smooth Gen5 trigger pull, ambidextrous slide stop lever, reversible magazine catch, and the precision-engineered GLOCK Marksman Barrel (GMB), offering outstanding accuracy and reliability.

The G45 MOS represents the next evolution in service pistols—battle-tested, operator-approved, and unmatched in performance.
