It can be removed and exchangedfor a barrel of a different caliber. The barrels have polygon profilebores.When converting to.22 LR, which is a rimfire round, the whole slide must also be exchanged. This second slideis part of the.22 LR conversion kit.

The.22 LR conversion barrelhas an unusual 'piston' in the end of the barrel with the actual.22 chamberin this piston, When the gun fires the chamber pressure is appliedto the entire area of the piston, and not just the cartridge. Thisprovides sufficient force to cycle the action.The P7K3 has an inertia blow-back action,unlike the gas-retarded action of the P7M8, etc. It uses uses a hydraulicslide buffer in place of the gas-retarding piston of the larger guns inthe family.

A gauge is supplied with the gun to see if the littlebuffer piston is still sticking out far enough. If it isn't, thenit is worn out. The piston could be replaced if HK would sell orgive you one - but they typically won't, so the gun is junk at that point.Checkthis when buying.Conversion KitsThe caliber conversion kits for the P7K3come in a box like this.This one holds both a.32 kit and a.22LR kit.

The.22 LR kit also includes a new slide, and a cleaningtool.22 LR ConversionThe conversion has a new slide to allowthe use of rim fire (vs. Center fire) ammo.The barrel is a bit unusual in that ithas a floating piston built into the end. A scraper tool is suppliedto scrape powder residue from the end of the barrel where the piston fitsand from the piston.When the round fires, the chamber pressureis applied to not just the area of the.22 LR cartridge head, but the areaof the whole piston. This generates a much higher force, which givesexcellent cycling with the.22 LR round.

It is much better that it'spredecessor (the HK4) which required hot ammo and a firm grip.VariationsThere are two variations of the P7K3 thatI know of (and have owned), the USA Model and the German Model. TheUSA Model was the only one imported by H&K themselves - other importerssuch as CCF imported the German Model.German Model:The gun comes with two magazines, thebarrel changing tool, a plastic box with the gun's serial number embossed,a manual and test target.Barrel markings.Note the one-piece metal rear sight, uniqueto the German Model.Note the almost flat grip, unique to theGerman Model.Importer, CCF RICHMONDVA engraved through bluing on this side.Also note the front sight is sloped onlyon the front edge.This side says HK Inc.Sterling VA, despite the CCF framemarkings. It appears to be part of the stamp that puts the HKlogo on.Note that only the serial number, datecode, and proofing marks are through the bluing. On the USA Model,The Sterling VA is stamped through the bluing.USA ModelThe USA model has a Wumpy-bump on theleft grip. Someone claimed the P7K3 was not USA-legal without it,didn't say why.It also has an adjustable (two positionelevation) plastic rear sight.The Sterling VA seems to be stampedthrough the bluing.Also note the front sight is sloped onboth front and rear edges.¤ ¤¤ ¤¤ ¤¤ ¤¤ ¤¤ ¤¤ ¤Copyright2000,2001,2002, 2003 All Rights Reserved.

Contents.History Prompted by the, the German police decided to replace the with a similarly sized but more effective pistol. The new firearm was to meet the following requirements: chamber the 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 and a service life of at least 10,000-rounds. 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.

As a result of a competitive bid the German police forces selected three different pistols into service: the Swiss (designated the P6) and two German designs—the P7 (officially designated the PSP) and the.Series production of the P7 started in 1979. Shortly after, the pistol was adopted by the counter-terrorism unit and the formations. The P7 was produced primarily by H&K but also under license by the Greek defense firm as well as in Mexico by the Departamento de Industria Militar (DIM), as a sidearm for general officers and staff. The pistol was also exported to several countries.Design details Operating mechanism. A schematic of the P7's system.The P7 is a firearm. 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 ), 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. 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.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.

The drawback of this system is that the breech 'opens' slightly prematurely to allow the slide to initiate its rearward motion. 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 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.

Features The P7's spring extractor is contained within the slide, while the fixed ejector is a surface on the slide catch.The grip of this pistol features a built-in cocking lever located at the front of the grip. Before the pistol can be fired, this lever must be squeezed; thus this lever acts as a safety. The pistol is striker fired. Squeezing the cocking lever with a force of 70 (15.7 ) cocks the firing pin.

Once fully depressed, only 2 pounds of force are required to keep the weapon cocked. 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. If the lever is released, the weapon is immediately de-cocked and rendered safe. This method of operation dispensed the need for a manual safety selector while providing safety for the user carrying the pistol with a chambered round, and increased the speed with which the pistol could be deployed and fired.

The trigger and firing mechanism's method of operation (and the unique slide catch) were protected by, issued on January 2, 1979.The P7 is fed from a single-stack with a capacity of 8 rounds, which is held inside the firearm's frame with a release located at the heel of the grip. After the last round has been fired, the slide will remain open thanks to a slide catch that can be released by pulling the slide further back or pressing the squeeze cocker.The firearm uses a fixed, barrel ( with a 250 mm twist rate) and a fixed notched with contrast dots that enable shooting in low-level lighting conditions. The pistol is completely ambidextrous and two-handed use is enhanced through the use of a profiled and enlarged trigger guard.Between 1982–1983 the P7 received several modifications, mainly to address American market demand and shooter preferences. These modifications resulted in the P7M8 model. A new magazine release lever (available on both sides of the frame) was installed just beneath the trigger guard, which forced designers to modify both the pistol's frame and magazine.

The trigger guard was equipped with a synthetic heat shield that protects the shooter from excessive heating and a lanyard attachment loop was added in place of the previous magazine heel release. The firing pin and its bushing were also changed.Variants.
