GLOCK 19 V The GLOCK 19 V pistol is versatile for many roles due to the reduced size. The frame design without finger grooves allows the user to customize the grip width to accommodate any hand size by mounting the different back straps. The reversible magazine catch is changeable at user level, as well as the ambidextrous slide stop lever to accommodate left and right-handed operators. The G19 V pistol features the GLOCK Marksman Barrel (GMB), 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.
