The G45 crossover configuration combines a compact-length slide with a full-size frame. This layout delivers a full-capacity grip with a shorter slide and incorporates a standard accessory rail on the dust cover.
Gen5 features include an updated frame with no finger grooves, a flared magwell, ambidextrous slide-stop levers, and a reversible magazine release. The frame uses the Modular Backstrap System to tailor grip size.
The slide and barrel wear Glock’s nDLC treatment, and the barrel is the Glock Marksman Barrel for enhanced rifling geometry. The slide has both front and rear serrations and a MOS optics cut with the cover plate installed.
Factory fixed 3-dot sights are installed. Capacity is 17+1 with the included 17-round magazine.
Manufactured in Austria, this pistol shows factory markings including MADE IN AUSTRIA, Glock, Inc., Smyrna, GA, U.S. Pat. 8,156,677, and Glock proofs on the barrel hood, with the left side of the slide marked "Glock 45 AUSTRIA 9x19."
