Glock G21 Gen5 MOS V 45 ACP 4.61" 13rd Optic Ready Pistol

The Glock G21 Gen5 MOS V brings the stopping power of the .45 ACP cartridge into Glock's latest V-series platform. The pistol features a 4.61" Glock Marksman Barrel (GMB) for improved accuracy, a flared magazine well for faster reloads, and an ambidextrous slide stop lever to accommodate both right and left handed shooters.

The Modular Optic System (MOS) slide is milled to accept a wide variety of micro red dot optics via Glock's included adapter plate set, while factory iron sights remain in place for backup use. The nDLC-finished slide resists wear and corrosion, and the Gen5 trigger system delivers a refined, consistent break well suited for duty, sport, and personal protection.

The Glock SAFE ACTION System uses three independent passive safeties that disengage sequentially as the trigger is pressed and automatically reset when released. The G21 Gen5 MOS V ships with three 13-round magazines and a full set of backstraps for customized ergonomics.
