Heckler & Koch HK4

Heckler & Koch HK4

The Heckler & Koch HK4 is a semi-automatic pistol that was manufactured by the German firearms company Heckler & Koch. It was introduced in the late 1960s and remained in production until the early 1980s.

Product Overview: HK4

The HK4 featured a modular design and came with interchangeable barrels, slides, and magazines, allowing the user to switch between different calibers. It was chambered for several popular pistol cartridges, including .22 LR, .25 ACP, .32 ACP, and .380 ACP. The pistol had a double-action/single-action trigger mechanism and a manual safety lever located on the left side of the frame.

One unique feature of the Heckler & Koch HK4 was its ability to change the entire upper slide assembly to accommodate different calibers. This made it a popular choice for users who wanted a single pistol that could be adapted for different purposes such as target shooting, self-defense, or plinking.
