Glock 17

 The Glock Safe Action pistol, popularly known as the Glock is a series of semi-automatic pistols designed and manufactured by Glock Ges.mbH, based in Deutsch-Wagram, Austria. The founder, Gaston Glock, an engineer, had no experience in design or manufacture firearms at the time their first pistol, the Glock 17, was prototype. Glock, however, have extensive experience in advanced synthetic polymers, whose expertise was instrumental in designing the company's first successful line of pistols with polymer frames. Glock introduced ferritic nitrocarburizing in the firearms industry as an anti-corrosion surface treatment for metal gun parts.

 Despite initial resistance from the market to a "plastic gun" to accept because of durability and reliability are concerned, Glock pistols have become the company's most profitable line of products, the commander of 65% of the market share of guns for the United State law enforcement agencies as providing many national armed forces and security agencies worldwide.

 The Glock 17 is a 9mm short locked breech recoil operated semi-automatic pistol that a custom Browning cam-lock system adapted version of the Hi-Power pistol used. The firearm locking mechanism uses a
link-less, vertical tilt barrel with a rectangular breech that well in the ejection port cut-out on the slide. During the recoil stroke, the barrel moves rearward initially blocked, along with the picture of about 3 mm (0.12 in), until the bullet leaves the barrel and chamber pressure drops to a safe level. A ramped lug extending at the base of the barrel than interacting with a tapered locking block integrated into the frame, barrel down and unlocking it from the slide. This camming action ends the course of the movement, while the picture stays back under recoil, extracting and ejecting the empty cartridge casing. The slides continuous backward motion and counter-recoil cycle are characteristic of the Browning system.

 The Glock 17 feeds from staggered-column or double stack magazines that a 17-round capacity (which can be extended to 19 with an optional floor) or the optional 33-round high capacity magazines have. For jurisdictions that restrict the magazine capacity to 10 rounds, Glock has a stack 10-round magazines. The blades are made of steel overmolded with plastic and. A steel spring drives a plastic follower. After the last cartridge is fired, the slide remains open on the slide stop. The slide stop lever is located on the left of the frame directly below the slide and can be manipulated by the thumb of the shooting hand.
The Glock 17 has a solid polymer-type combat perception package that includes a rising front sight and a notched rear sight with white contrast elements painted on for increased acquisition speed, a white dot on the front post and a rectangular framework the rear notch. The rear sight can be adjusted for wind correction as it has a certain amount of lateral movement in the dovetail is mounted in. Three other factory rear sight configurations are available in addition to the standard 6.5 mm (0.26 in) height sight: a lower Impact 6.1 mm (0.24 in) visibility and greater impact two versions 6.9 mm (0.27 in) and 7.3 mm (0.29 in).

The Glock 17 9x19mm Parabellum is the original model with a standard magazine capacity of 17 rounds. Some modified versions of the Glock 17 introduced.

• The Glock 17C was introduced in 1996 and included slots cut into the barrel and slide to compensate for muzzle rise and recoil. Many other Glock pistols now come with this option, all with a "C" suffix on the slide.

• The Glock 17L was introduced in 1988 and has a longer slide and extended barrel. Initially, the Glock 17L had three holes in the top of the vessel and a corresponding slot in the slide, but later production pistols lack the holes in the barrel. The Glock 17L is effectively stopped and put replace the Glock 34.

• The Glock is a 17MB version with symmetrical magazine catch. The Glock 19 and Glock 21SF-MB are available as options.
