Glock G45 MOS 9mm 4.02" Black nDLC 17+1 PA455S203MOS

G45 MOS

The Glock G45 MOS is a compact crossover pistol that blends the reliability and accuracy expected from Glock with versatile features for various shooting needs. Chambered in 9mm Luger, it features a 4.02-inch Glock Marksman Barrel for enhanced precision and a Modular Optics System for easy mounting of red dot sights. This Gen5 model combines a compact slide with a full-size frame, offering a balanced design suitable for law enforcement, competitive shooting, and personal defense.

Key enhancements include front slide serrations for improved grip during manipulation, a flared magwell for faster reloads, and black textured interchangeable backstraps for a customizable fit. The black nDLC finish on the steel slide provides superior corrosion resistance and a non-reflective surface, while the polymer frame with Picatinny rail allows for accessory attachments. Integrated safeties—trigger, firing pin, and drop—ensure secure operation, and the DAO action delivers consistent performance with every pull.

Ideal for concealed carry, duty use, or range sessions, the G45 MOS excels in scenarios requiring quick target acquisition and reliability under stress. Its lightweight 30.34-ounce construction and 17+1 capacity make it a practical choice for operators and enthusiasts who value modularity and proven Glock engineering in dynamic environments.
