The Glock 45 Gen 5 is a crossover service platform that pairs a full-size grip module with a reduced-length slide to improve handling and follow-up accuracy. Gen 5 updates remove finger grooves, standardize frame texture, and use the Glock Marksman barrel profile to improve consistency and accuracy across duty roles.

This example is configured with a 4.02 in Marksman barrel and an nDLC-finished steel slide with an RMR cut for mini reflex sights. Controls include the Safe Action trigger system, reversible magazine catch, ambidextrous slide stop, forward and rear slide serrations, and a flared magazine well. Sights are suppressor-height factory style. This pistol's frame also features a trigger guard undercut, aiding in comfort and connection to the firearm. Includes original case and two 17-round magazines.
