Chambered in .45 GAP, this Gen 3 Glock G37 uses the classic Gen3 grip frame with finger grooves and a single-slot accessory rail. It does not use interchangeable backstraps, and it retains Glock’s proven Safe Action system in a striker-fired configuration.
The pistol wears fixed Glock polymer sights with a white-dot front and white-outline U-notch rear. A 6.50 in sight radius supports clear sight alignment. The slide has rear-only vertical serrations and a right-side ejection port for consistent manipulation and ejection.
The extended slide stop lever is installed for easier slide release, and the removable rubberized grip sleeve adds a tacky, hand-filling feel over the factory polymer frame. Capacity is 10+1 with the included factory magazine, and the steel barrel measures 4.49 in.
Markings include "GLOCK 37 AUSTRIA 45 GAP" on the slide and ".45 G.A.P." on the barrel. The frame bears "GLOCK, INC., SMYRNA, GA." markings. Major components carry matching serial numbers, adding confidence in the pistol’s as-issued configuration.
