The Glock 21 SF Gen 3 combines the .45 ACP chambering with the Short Frame grip profile, delivering a reduced trigger reach and a flatter backstrap on a full-size frame. This example retains the Gen3 Glock universal rail (single slot) and rear slide serrations, with a black slide and polymer frame.
The 4.6" cold hammer-forged barrel uses Glock’s polygonal rifling, designed for durability and consistent bore finish. The striker-fired, short-recoil, tilting-barrel action provides the familiar Gen3 operating system.
Aftermarket enhancements include extensive grip stippling that adds aggressive texture to the polymer frame, and fixed TruGlo TG-H3 tritium/fiber-optic 3-dot sights for a bright sight picture in varied lighting.
Factory markings include "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." on the frame. The slide, barrel, and frame show matching serial numbers, and the included 10-round Glock factory magazine is Austria-marked with a steel liner.
