Glock G21 G5 MOS Features
The Glock G21 G5 MOS is designed for shooters who prioritize stopping power and adaptability. Chambered in .45 ACP, it uses Glock’s Safe Action® trigger system and a 4.61-inch barrel to deliver dependable accuracy and recoil control. The Modular Optics System (MOS) slide cut allows for mounting a variety of micro red dot optics, while factory fixed Glock sights remain in place for co-witness or backup aiming.
This Gen5 model features multiple enhancements including front slide serrations, a flared mag-well for improved reload speed, and the elimination of finger grooves for a more customizable grip. The Grey Cerakote finish applied to the slide adds a modern, tactical appearance and increased surface durability. Supplied with three 13-round magazines and housed in a Glock-branded plastic case, this pistol is ideal for duty, personal defense, or range use.
