Dragon DRA1302 Glock G17 Semi Automatic Hand Guns with Tactical Light amd Gun Case Kit (1:3 Scale)
"Obsolete weapons do not deter."

Glock is the name of a family of pistols designed and produced by the Austrian company Glock GmbH of Deutsch-Wagram, founded in 1963 by engineer Gaston Glock to manufacture high-strength synthetic and steel components.
The Glock 17 (so named because it was the 17th patent of the company) is a 9 mm short recoil-operated locked breech semi-automatic pistol that uses a modified Browning cam-lock system adapted from the Hi-Power pistol. The firearm's locking mechanism utilizes a linkless, vertically tilting barrel with a rectangular breech that locks into the ejection port cut-out in the slide. During the recoil stroke, the barrel moves rearward initially locked together with the slide approximately 3 mm (0.12 in) until the bullet leaves the barrel and chamber pressure drops to a safe level. A ramped lug extension at the base of the barrel then interacts with a tapered locking block integrated into the frame, forcing the barrel downward and unlocking it from the slide. This camming action terminates the barrel's movement while the slide continues back under recoil, extracting and ejecting the spent cartridge casing. The slide's uninterrupted rearward movement and counter-recoil cycle are characteristic of the Browning system.
The slide features a spring-loaded claw extractor and the stamped sheet metal ejector is pinned to the subframe. The striker firing mechanism has a spring-loaded firing pin that is cocked in two stages, powered by the firing pin spring. When the pistol is charged, the firing pin is in the half-cock position. As the trigger is pulled, the striker is fully cocked. At the end of its travel, the trigger bar is tilted downward by the disconnector, releasing the striker to fire the cartridge. The disconnector also resets the trigger bar so that the striker will be captured in half-cock at the end of the firing cycle. This is known as a pre-set trigger mechanism, referred to as the "Safe Action" trigger by the manufacturer. The disconnector also ensures the pistol can only fire in semi-automatic mode.
The Glock features a triple safety system that secures the firearm against accidental discharge and consists of three independent safety mechanisms: an external trigger safety and two automatic internal safeties - a firing pin safety and a drop safety. The external safety is a small inner lever contained in the trigger. Pressing the lever activates the trigger bar and sheet metal connector. One of the internal safeties is a solid hardened steel pin that, in the secured state, blocks the firing pin channel (disabling the firing pin in its longitudinal axis). The firing pin safety is only pushed upward to release the firing pin for firing when the trigger is actuated and the safety is pushed up through the backward movement of the trigger bar, the second, drop safety guides the trigger bar in a precision safety ramp that is only released when a shot is triggered by pulling the trigger right back. The safeties are systematically disengaged one after another when the trigger is squeezed and then automatically re-activated when the trigger is released. This triple safety system guarantees safe handling with a cartridge introduced into the chamber, reducing the time required to deploy the pistol. This allows the user to concentrate on tactical considerations, rather than manipulation of levers, hammers or external safeties found in other, conventional handguns. However, in the case of a misfire this design provides no way to re-cock the striker without manipulating the slide and ejecting the unfired cartridge.
The cold hammer-forged barrel has a polygonal profile bore with a right-hand twist. The rifling's polygonal profile consists of a series of six small arcs (eight for .45 calibers) connected by flat surfaces. This provides a better gas seal around the projectile, greater consistency in velocities, increased accuracy and ease of maintenance. One problem with a polygonal barrel is the tendency of soft lead bullets to deposit lead in the bore. This has been known to cause damage to the barrel, often bursting the barrel and causing damage to the pistol and injuries to the shooter. Glock warns against using reloaded ammunition.
The Glock's frame, magazine body and several other components are made from a high-strength nylon-based polymer. The injection molded frame contains 4 hardened steel guide rails for the slide: two at the rear of the frame, and the remaining pair above and in front of the trigger guard. The trigger guard itself is squared off at the front and checkered. The grip has a non-slip, stippled surface on the sides and both the front and rear straps. The frame houses the locking block, which is an investment casting that engages a 45 camming surface on the barrel's lower camming lug. It is retained in the frame by a steel axis pin that also holds the trigger and slide catch. The trigger housing is held to the frame by means of a plastic pin. A spring-loaded sheet metal pressing serves as the slide catch, which is secured from unintentional manipulation by a raised guard molded into the frame.
The rectangular slide is milled from a single block of ordnance-grade steel using CNC machinery. The barrel and slide are finished with a proprietary nitriding process called Tenifer. Three hardening processes are applied to the slide and barrel prior to the final nitride bath. The Tenifer finish is approximately 0.5 mm (0.02 in) in thickness and is characterized by its extreme wear and corrosion resistance. The Tenifer process produces a matte, non-glare surface with a 64 Rockwell C hardness rating and a 99% resistance to salt water corrosion (which meets or exceeds stainless steel specifications).
A current production Glock 17 consists of 34 parts. For maintenance, the pistol disassembles into five main groups: the barrel, slide, frame, magazine and recoil spring assembly.
Length: 2-1/2 inches
Historical Account: "Feeding Frenzy" - The Glock 17 feeds from a double-column box magazine with a 17-round capacity or an extended 19-round magazine. Magazines feature a steel body overmolded with plastic. A steel spring drives a plastic follower. After the last cartridge has been fired, the slide remains open on the slide stop. The slide stop release lever is located on the left side of the frame directly beneath the slide and can be manipulated by the thumb of the shooting hand.
The Glock 17 has a fixed polymer combat-type sighting arrangement that consists of a ramped 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 border on the rear notch. The rear sight can be adjusted for windage as it has a degree of lateral movement in the dovetail it is mounted in. Three different factory rear sights are available apart from the standard 6.5 mm (0.26 in) height sight: a lower impact 6.1 mm (0.24 in) sight and two higher impact versions—6.9 mm (0.27 in) and 7.3 mm (0.29 in). Adjustable and illuminated night sights are also offered.
