The new frame design of the GLOCK 17 Gen5 removed the finger grooves for more versatility but still allows it to easily customize its grip using 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 the user level, and the ambidextrous slide stop lever accommodate left and right-handed operators. The barrel’s rifling and crown were slightly modified for increased precision.
