The G45 crossover design pairs a compact-length slide with a full-size frame, delivering a 17+1 capacity with a comfortable, full-hand grip. Gen5 ergonomics include no finger grooves, a flared magwell, and the latest Gen5 texture for secure control.
The factory MOS slide has the cover plate installed and features both front and rear serrations. Glock's black nDLC finish adds durability and corrosion resistance. Matching serial numbers are present on the barrel, slide, and frame.
The 4.02 in Glock Marksman Barrel (GMB) uses enhanced rifling for performance and consistency. The striker-fired Safe Action system pairs with a revised trigger geometry and an approximate 5.8 lb trigger pull. Controls include an ambidextrous slide stop lever and a reversible magazine catch.
Fixed polymer sights with a white-dot front provide a straightforward sight picture. A standard Glock accessory rail on the dust cover supports common weapon-mounted lights. This pistol is made in Austria and maintains the familiar Glock reliability and handling.
