The Gen 3 subcompact frame features finger grooves, a single-sided slide stop, and the small Gen 3 magazine catch. It retains Glock's Safe Action system in a striker-fired format and omits an accessory rail, aligning with early Gen 3 subcompact configuration.
The 3.42-inch steel barrel uses polygonal rifling with a right-hand twist. The slide wears Glock's Tenifer (ferritic nitrocarburizing) finish, and the overall package provides a 9+1 capacity in .40 S&W.
Sights are the standard fixed polymer notch-and-post set, offering a clear, familiar sight picture.
Markings include a molded frame import legend reading "MADE IN AUSTRIA / GLOCK, INC., SMYRNA, GA," and a proof mark on the barrel lug. The frame, barrel, and slide share matching serial numbers by root. An aftermarket 9mm threaded conversion barrel is included for caliber flexibility; its lug is marked '40-9mm' and a knurled thread protector is installed.
