Weapon: HK 4

Description:

The pistol HK 4 is a marvel of the technology of the time!   After the war, some engineers got together and founded Heckler & Koch (H&K). Some of them had previously worked at Mauser and were involved in the development of the Mauser Hsc pistol there. This also explains the direct technical descent of the HK 4 from the Mauser Hsc.   It is an unlocked recoil loader with a spring-mass bolt action. It features a cocking trigger with a combined safety-release device.   The HK 4 has the number "four" in its name because it can be quickly and easily converted to four different calibers. By changing the barrel and magazine (when changing from centerfire caliber to rimfire caliber, the firing pin must still be changed), the calibers .22 Long Rifle (.22 LR), 6.35mm Browning, 7.65mm Browning and .380 Auto can be fired from the pistol. Some of these interchangeable barrels have the same number as the gun (rare) or then have their own numbers in the range greater than 100,000.   The HK 4 is a weapon from the beginning of Heckler and Koch's weapon production; it was eventually further developed into the HK P9.   The HK 4 was produced for the private market and the government market. For the private market, a normal and an anniversary series (100 years of H&R) were imported by the American manufacturer/importer H&R Firearms (formerly Harrington & Richardson), which have their own serial number range.   Numbers HR 00001 through HR 02000 were manufactured as 100th Anniversary H&R pistols. Numbers HR 02001 through HR 10000 were standard pistols for the American civilian market. Numbers 10001 through 40000 were for civilian HK 4 pistols. Numbers 40001 through 52400 were intended for German customs and police agencies (last known number in November 1974).   555 pistols were fabricated by the French factory MAS (numbers 51566 to 52120 in 1973 and 1974). These were intended for the Berlin authorities, who were not allowed to carry German weapons due to Allied regulations. The interchangeable barrels bear serial numbers greater than 100000.   For the pistols of the German authorities, which had the caliber 7.65mm Browning, very few barrels with the same number in the caliber .22 Long Rifle (.22 LR) were delivered.   The HK 4 from the government sector do not show civilian German proof marks in their original condition.
