Design and Key Features

The GLOCK G21 GEN 4 in .45 ACP marries Glock’s time-tested reliability with user-focused upgrades. The 4.61″ barrel length delivers consistent accuracy and sight radius advantageous for both duty and range work. A 13-round magazine capacity provides substantial firepower in a large-caliber package, and the Gen 4 enhancements—modular backstrap system, improved recoil spring assembly, and reversible magazine catch—make it adaptable for different shooters and holster setups.

Caliber Advantages and Practical Applications

The .45 ACP remains favored for its knock-down performance and terminal characteristics. In practical terms, the caliber offers predictable recoil impulse and effective energy transfer at typical engagement distances. For home defense, security detail, or back-up duty use, the G21 Gen 4’s .45 ACP profile provides confidence when a decisive, single-shot response is required.

Ergonomics, Durability, and Finish

Ergonomics on the Gen 4 platform are a step forward—interchangeable backstraps let shooters tune grip circumference, while the reversible magazine catch accommodates left- and right-handed manipulation. The improved recoil spring assembly reduces felt recoil and prolongs service life under intensive use. The distinctive Coyote Tan finish not only offers a unique aesthetic but also reduces visual contrast in field or tactical environments, an asset for concealed duty or low-profile carry.

Price for this configuration is $749.99, a competitive value given the large-frame caliber, Gen 4 upgrades, and the specialized finish. For full specifications and purchase options, View product details and pricing.
