The frame design of the Glock 21 MOS V Series is the latest innovation in Glock pistols. The biggest change in the V Series from the Gen 5 is internal upgrades to the slide and trigger. Just like the Gen 5, they removed the finger grooves for more versatility but still allows to easily customize its grip by using the different back straps. A flared mag-well and a cutout at the front of the frame give the user more speed during reloading when fractions of a second matter. A reversible enlarged magazine catch, changeable at user level as well as the ambidextrous slide stop lever accommodate left and right-handed operators. The rifling and the crown of the barrel were slightly modified for increased precision. FeaturesOptics Ready NDLC finished SlidePolymer frame with accessory railInterchangeable backstrap set
