Glock 21 Gen 5 Full Size Mos .45 ACP 4.61 inch 13+1 Capacity

The Glock 21 Gen 5 G5 FS MOS 13R combines the long-established reliability of the Glock platform with the .45 ACP's stout stopping power and a 13+1 capacity that suits duty, home defense, concealed carry, and range work, and it requires FFL transfer. This Gen 5 semi-auto pistol features Safe Action internals and a dual recoil spring assembly to reduce felt recoil and prolong service life, while the MOS cut provides rapid optics mounting for modern defensive setups. Shooters will appreciate the modular interchangeable backstrap system and Gen 5 rough textured frame for consistent grip control across hand sizes and conditions, and the reversible enlarged magazine catch allows fast-handed reloads for left- or right-handed operators. The 4.61" barrel and serrated slide deliver predictable accuracy and reliable slide manipulation, and the integrated firing pin/trigger safety block adds an extra layer of passive drop protection. Whether issued for duty, carried as a defensive handgun, or used for serious training at the range, the Glock 21 Gen 5 delivers rugged performance and practical ergonomics that seasoned shooters and newcomers both value.
