The G45 crossover design mates a compact-length 4.02 in slide to a full-size frame, offering a controllable grip with 17+1 capacity. The frame uses an RTF-style texture and the Modular Backstrap System, with two additional backstraps included to tailor fit and reach.
Gen5 features include the Glock Marksman Barrel with enhanced polygonal rifling and a target-style crown, and a durable nDLC black finish on both slide and barrel. The slide adds forward serrations and a chamfered nose for streamlined handling.
The factory MOS interface is present with the cover plate installed, ready for the mounting system you choose. Controls include ambidextrous slide stop levers, and the Safe Action System with an approximate 5.5 lb trigger.
Sight configuration is straightforward and fast: a fixed white-dot front and white-outline U-notch rear. This pistol is made in Austria, carries the Glock, Inc., Smyrna, GA import mark, and has matching serial numbers on the frame and slide.
