The G21 Gen4 is a full-size .45 ACP with a 4.61 in barrel and a 13+1 capacity. This example is Austrian-made and marked accordingly with "MADE IN AUSTRIA" and "GLOCK, INC., SMYRNA, GA." Its steel slide wears a light tan/silver finish that contrasts with the black polymer frame.
Upgraded TRUGLO TFO sights combine tritium with fiber-optic elements in a fixed 3-dot configuration, with the front blade marked "TFO-H3." The long 6.77 in sight radius supports precise alignment.
Gen4 features include the modular backstrap system (MBS), an enlarged and reversible magazine catch, and a dual recoil spring assembly. The frame integrates a Glock accessory rail (single slot) for compatible lights or accessories.
The steel barrel uses right-hand twist with octagonal rifling. Matching serial numbers are present on the slide window/barrel hood, frame, and dustcover serial plate. Enhancements include an aftermarket trigger shoe with a red safety tab and a Pachmayr wrap-around rubber grip sleeve for a secure hold.
