Glock G21 G5 MOS Features
The Glock G21 G5 MOS is engineered for shooters who demand high-caliber performance and modern modularity. Chambered in .45 ACP, it utilizes Glock’s Safe Action® system and a refined 4.61-inch barrel for dependable precision and reliable recoil management. The Modular Optics System (MOS) allows seamless mounting of micro red dot sights, while fixed Glock sights provide a reliable backup sighting option.
This Gen5 variant includes several ergonomic and tactical enhancements, such as front slide serrations, a flared mag-well for faster reloads, and the removal of finger grooves for a more universal grip. The FDE Cerakote finish, applied to both the slide and frame, adds a rugged, low-profile aesthetic and superior durability. Supplied with three 13-round magazines and a plastic case, the G21 G5 MOS is a top-tier choice for defensive carry, duty use, or range performance in a hard-hitting .45 platform.
