Performance and Caliber

The .45 ACP is prized for its terminal performance and controllable recoil when paired with the right platform. The GLOCK G21’s 13-round magazine provides a solid balance between capacity and the larger .45 ACP cartridge. Expect effective stopping power for defensive roles, close-quarters scenarios, and duty use, while the Gen 4 recoil spring assembly helps tame follow-up shots and lengthens component life for sustained training cycles.

Ergonomics and Controls

The Gen 4 modular backstrap system allows shooters to quickly change grip circumference for better index and control. The enlarged and reversible magazine catch makes reloads more intuitive for left- or right-handed users. The rough textured technology on the frame provides a secure purchase in wet or gloved conditions without aggressive wear on clothing.
