This is the Glock 21SF Short Frame variant, designed to reduce grip circumference and trigger reach compared to the standard 21 while retaining the full-size format. It is chambered in .45 ACP with a 13+1 capacity and uses Glock's Gen 3 frame with finger grooves and checkered front and back straps.
The 4.6 in steel barrel features Glock's polygonal rifling. The striker-fired, short-recoil action works in concert with the Safe Action system, which employs three passive safeties for consistent operation.
Sights are fixed polymer: a front post with a white insert and a rear polymer unit with a white U-notch. The slide has rear-only vertical serrations for manipulation.
The frame includes a Glock-pattern accessory rail with a single cross slot. The magazine release is on the left side, in keeping with Gen 3 configuration.
Origin and markings are clear: the frame carries the molded legend "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA.", the slide is marked "AUSTRIA," and the barrel hood bears an AT marking. This example was manufactured in Austria and imported by Glock, Inc., Smyrna, GA.
