Austrian manufacture with U.S. import markings adds clear provenance, and it comes with two 10-round factory magazines and an installed Streamlight TLR-7A on the Glock Universal rail.

The G21 SF (Short Frame) configuration reduces grip circumference and trigger reach compared to the standard frame, while retaining the Gen3 frame with molded finger grooves and no interchangeable backstraps. The left-side-only magazine release and rear slide serrations reflect the Gen3 control layout.
Chambered in .45 ACP, this striker-fired pistol uses Glock’s Safe Action system and a short-recoil, tilting-barrel Browning-type lockup. The 4.61 inch steel barrel uses polygonal rifling, and the pistol is paired with fixed polymer sights: a white-dot front post and a rear notch.
Capacity is 10+1, and this example includes two Glock factory 10-round magazines. The frame integrates the Glock Universal single cross-slot accessory rail, and a Streamlight TLR-7A is installed on the rail for immediate use.
The slide and barrel wear a nitrocarburized finish. Markings include "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." and an "AT" stamp on the barrel hood, indicating Austrian manufacture with U.S. import marking.
This is a discontinued model, combining the SF grip geometry with Gen3 features that many shooters and collectors look for in this .45 ACP platform.
