The G21 V MOS is chambered in .45 AUTO and delivers accuracy and light recoil. The reversible magazine catch and ambidextrous slide stop lever make it ideal for left and right-handed shooters. The G21 V pistol features the GLOCK Marksman Barrel, nDLC surface finish, front serrations, an ambidextrous slide stop lever, and more.
The SAFE ACTION® System is a fully automatic safety system consisting of three passive, independently operating, mechanical safeties. All three safeties disengage sequentially as the trigger is pulled and automatically re-engage when the trigger is released.
