Overview
Released around 2012 as part of the broader Gen4 rollout, the Glock 21 Gen 4 updated the popular 13-round .45 ACP duty pistol with a dual recoil spring assembly, modular backstrap system (MBS), and a larger, reversible magazine catch. These changes improved recoil management and ergonomics over previous models.
