The Glock 17 is a semi-automatic 9 mm short-recoil-operated, locked-breech pistol using a modified Browning cam-lock system adapted from the Hi-Power pistol. A linkless, vertically tilting barrel with a rectangular breech that locks into the ejection port cut-out in the slide is used by the locking mechanism of the weapon. The barrel travels backward initially locked together with the slide around 3 mm (0.12 in during the recoil stroke before the bullet exits the barrhttps://deepwebguns.com/product/glock-17-gen5/el and the pressure of the chamber decreases to a At the base of the barrel, a ramped lug extension then interacts with a tapered locking block built into the frame, pressing the barrel down and unlocking it from the slide. This camming action terminates the movement of the barrel as the slide continues back under recoil, removing the spent cartridge casing and ejecting it. The Browning mechanism is characterised by the slide’s uninterrupted rearward movement and counter-recoil period.
