The G45’s crossover design delivers a compact 4.02" slide on a full-size frame for a balanced 9mm platform. The Glock Marksman Barrel and nDLC treatment on both barrel and slide support durability and consistency. Front and rear slide serrations aid manipulation, and the slide is factory cut for MOS.
Gen5 updates are present throughout: no finger grooves, a flared magwell, ambidextrous slide stop levers, and a reversible magazine catch. The Modular Backstrap System with aggressive micro-texture allows straightforward grip customization, and two backstrap inserts are included.
Factory sights include a white dot polymer front and a white U-notch polymer rear marked 6.1. The frame is glass-fiber-reinforced polymer in black with an integrated accessory rail. The Safe Action System and striker-fired operation maintain the consistent Glock handling buyers expect, with a listed trigger weight of 5.8.
Markings include Austrian proof marks on the barrel hood and the "MADE IN AUSTRIA" with GLOCK, INC., SMYRNA, GA importer designation. Serial numbers match on the slide, barrel, and frame. Standard capacity is 17+1.
