If the lever is released, the weapon is immediately de-cocked and rendered safe. The weapon is then fired by pressing the single stage trigger rated at approximately 20 N (4.5 lb f) As long as the lever is depressed, the weapon fires like any other semi-automatic pistol. Once fully depressed, only 2 pounds of force are required to keep the weapon cocked. Squeezing the cocking lever with a force of 70 N (15.7 lb f) cocks the firing pin. Before the pistol can be fired, this lever must be squeezed thus this lever acts as a safety. The grip of this pistol features a built-in cocking lever located at the front of the grip. The P7's spring extractor is contained within the slide, while the fixed ejector is a surface on the slide catch. The advantages of this system are a simpler manufacturing process due to the absence of a locking system and a high mechanical accuracy due to the barrel being fixed in the frame the barrel does not execute any sort of lateral or vertical movement during the operating cycle as with the Browning cam-action systems common to many other locked breech pistols. The high temperature gases cycling through a tube located below the chamber area and above the trigger made the early versions of this pistol uncomfortable, according to some, to shoot after the content of two magazines were fired due to heating. The drawback of this system is that the breech "opens" slightly prematurely to allow the slide to initiate its rearward motion. The chamber has 18 flutes that aid in the extraction process by allowing combustion gases to flow between the fired case and the chamber walls, preventing the case from "sticking" to the chamber walls.
This is accomplished by means of a piston contained inside a cylinder located under the barrel that opposes the rearward motion of the slide until the gas pressure has declined-after the bullet has left the barrel-hence allowing the slide to end its rearward motion, opening the breech and ejecting the empty cartridge case.
It features a unique gas-delayed blowback system modeled on the Swiss Pistole 47 W+F (Waffenfabrik Bern) prototype pistol (and ultimately on the Barnitzke system first used in the Volkssturmgewehr 1-5), which used gas pressures from the ignited cartridge and fed them through a small port in the barrel (in front of the chamber) to retard the rearward motion of the slide. The P7 is a semi-automatic blowback-operated firearm. Design details Operating mechanismĪ schematic of the P7's gas-delayed blowback system. The pistol was also exported to several countries.
#HK P7 GRIPS LICENSE#
The P7 was produced primarily by H&K but also under license in Mexico by the Departamento de Industria Militar (DIM), as a sidearm for general officers and staff. Shortly after, the pistol was adopted by the German Federal Police's counter-terrorism unit ( GSG 9) and the German Army's special forces formations.
#HK P7 GRIPS SERIES#
Series production of the P7 started in 1979. As a result of a competitive bid the German police forces selected three pistols into service: the Swiss SIG Sauer P225 (designated the P6) and two German designs-the P7 (officially designated the PSP) and the Walther P5. The pistol was also to be fully ambidextrous, safe to carry with a loaded chamber (both holstered and concealed in a pocket), and able to be quickly drawn and instantly ready to fire. The new firearm was to meet the following requirements: chamber the 9×19mm Parabellum cartridge, weigh no more than 1,000 g (35 oz), the pistol's dimensions would not exceed 180 × 130 × 34 mm, it should have a muzzle energy of no less than 500 J and a service life of at least 10,000 rounds. 32 ACP Walther PP with a similarly sized but more effective 9×19mm Parabellum pistol. Prompted by the 1972 Munich Olympics Massacre, the German police decided to replace the. Army XM9 pistol trials as a replacement for the M1911 pistol.
The P7M13, a variant of the P7 with a double-stack magazine, was produced until 2000, and was unsuccessfully submitted to the U.S.
#HK P7 GRIPS PSP#
It was revealed to the public for the first time in 1976 as the PSP ( Polizei-Selbstlade-Pistole-"police self-loading pistol"). The Heckler & Koch P7 is a German 9×19mm semi-automatic pistol designed by Helmut Weldle and produced from 1979 to 2008 by Heckler & Koch GmbH (H&K).
