For 2019, all Glock Gen5 pistols are now produced with front serrations and a Mod1 frame, which removes the half-moon cut out at the base of the frame.

The new frame design of the GLOCK 17 Gen5 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.
