The P7K3 is a shortened version of the P7 (inspired by the HK4 pistol) that uses straight blowback for operation. This version has a removable barrel and uses a sealed hydraulic recoil buffer in place of a gas cylinder. The hydraulic recoil buffer of the P7K3 is prone to wear and causes a serious problem to operate the gun when it is worn down. Heckler & Koch does not make a replacement part for the buffer. However, there are some commercial buffers available. When the .22 Long Rifle slide and barrel are installed, the buffer is not engaged. The slide of the .22 Long Rifle has an opening at the front that allows the buffer to be unused when firing the gun. Heckler & Koch provides a special scraper tool for the .22 Long Rifle barrel. The tool is needed to clean the inside of the floating chamber for safe operation. An additional exchange tool is provided for all calibers to screw and unscrew the barrel nut that attaches the barrel to the frame.
P7K3's are more rare in the U.S. than in Europe and are valued at higher prices especially when they are in good condition.
Heckler & Koch was founded in 1949 by engineers Edmund Heckler (1906-1960), Theodor Koch (1905-1976), and Alex Seidel (1909-1989) formerly of the Mauser rifle company.
Designed by Helmut Weldle.
