What’s Included
- Glock G21 SF Gen3 .45 ACP pistol
- Three 10-round Glock factory polymer .45 Auto magazines
The SF (Short Frame) variant reduces trigger reach compared to the standard frame, offering a shorter grip circumference while retaining the full-size G21 slide and 4.6-inch barrel. It is a straightforward, striker-fired setup in .45 ACP with a listed 6.3 lb trigger weight.
This Gen3 configuration provides the familiar finger-groove grip without interchangeable backstraps. The frame is polymer with the Glock Universal single-slot accessory rail and a standard left-side-only magazine release.
The slide uses rear serrations only, and the sighting setup is Glock’s polymer notch-and-post system with a white-dot front and a white-outline rear for quick sight reference.
Markings include "AUSTRIA" on the slide and "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA" on the frame. The slide, barrel, and frame carry matching serial numbers, adding to the desirability for those who value component consistency.
