The new frame design of the Glock 17 Gen 5 removed the finger grooves for more versatility but still enables you to easily customize your grip by using the included back strap options. 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. Firearm Specifications
