The .45 ACP remains a benchmark cartridge for defensive use, and when paired with a proven platform it becomes a tool you can trust. This review examines the design choices, control features, and field applications that make a large-caliber pistol both practical and effective for professionals and serious enthusiasts.

GLOCK G21 GEN 4

Performance and handling

The GLOCK G21 GEN 4 in .45 ACP pairs a 4.61″ barrel with Glock’s long-established striker-fired platform to deliver consistent accuracy and reliable service life. The 4.61″ barrel length balances pointability and sight radius, which helps tighten groups at typical engagement distances. The .45 ACP caliber provides strong terminal performance and operates subsonically in many loads, which can be beneficial if suppressor use or reduced noise signature is a consideration.

Ergonomics and modularity

Recoil management and magazines

An improved recoil spring assembly in the Gen 4 reduces felt recoil and extends service life under heavy use. Combined with a 13-round magazine capacity, the G21 Gen 4 offers stout firepower in a service-oriented package without sacrificing control.

For professionals who value concealability in certain roles, the Coyote Tan finish reduces glare and lowers visual contrast in outdoor environments while delivering an exclusive look compared to standard black models.
