HK 4

The HK 4 pocket pistol was first introduced by Heckler and Koch in 1967 making it the first pistol produced by the company. Mass production of this pistol started in 1968 and continued until 1984. There were approximately thirty-eight thousand pistols produced during this time. Twelve thousand of these pistols were sold to German police and other government agencies with the .32ACP caliber and are designated HK 4 P11. An additional 2000 were made around 1971 as a commemorative set with a golden trigger and gold name plate. The HK 4 was designated 4 because the pistol had the ability to be modular. This meant that the pistol could accommodate 4 different calibers by a simple replacment of the barrel, return spring, and the magazine. The four calibers that the pistol could use are: 5.6mm rimfire/.22LR; 6.35x16SR/.25ACP; 7.65x17SR/.32ACP; 9x17/.380ACP (9mm). Most pistols were sold as .380ACP (9mm) or .32ACP; the other 3 calibers were sold as a kit with the appropriate barrels and magazines. This is a double action pistol meaning it is cocked and fired with the trigger for the first shot. It is thought that the design of the HK 4 is based on that of the Mauser HSc.
