Our Assessment: Today, Heckler & Koch is well known as a pistol manufacturer from their USP series to the more modern P30 and VP series. In the mid-60s, however, they had never made a pistol. Heckler & Koch, quite literally, rose from the rubble of WWII, creating a metal fabrication company with what machines could be recovered from the Oberndorf Mauser factory. Initially producing parts for sewing machines and bicycles, and they did not begin producing firearms until the ’50s, when they came out with the G3 in response to a request from the newly formed Bundeswehr. It was not until 1966 that H&K began looking into producing pistols with the HK4 being their first offering in 1968. The name came from the pistol’s ability to accept four different barrels in four different cartridges: .22, .25, .32 and .380. By changing the barrel, recoil spring and magazine, the pistol could be swapped between these cartridges at will, allowing for inexepensive practice, use of different cartridges based on availability and price. Though perhaps not as well known as pistols such as the PPK or HSc, the HK4 was nonetheless a commercial success and saw adoption by the German Custom Police. This example, with its “BUND BZV” marking, appears to have been initially made for the German government, but later was slated for export to the United States under HK Inc. The pistol is in about Very Good-plus condition with matching serial numbers on most parts except for the .380 barrel, light finish wear and great bores. If you get a .25 ACP barrel set and magazines, you’ll have the whole set, but as it sits it can shoot three of the more common compact pistol calibers and is a great example of HK’s first foray into the pistol market. Please see our photos and good luck!
