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, 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 1967. 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 inexpensive 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 is from very early in production, before the need for import marks and with importation performed by Harrington & Richardson. The pistol is in about Excellent condition with barrels and magazines for all four cartridges, matching test-targets, and everything you need to use all four except for the rimfire striker assembly. This is a great example of HK’s first foray into the pistol market in great condition and with proper boxes for storage and display. Please see our photos and good luck!
