The Glock is universally regarded as the most reliable pistol in the world. All Glock pistols are equipped with the "Safe Action" System which consists of three passive safeties (trigger, firing pin, drop), eliminating the need for an external safety and simplifying the operation of the firearm. Glock frames are made of highly resistant reinforced polymer, reducing pistol weight and significantly increasing durability. Its polymer makeup gives it resistance to all climates, corrosion, and lubricants.
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.
