How a Walther PPK Works

The most common variant is the Walther PPK, a smaller version of the PP with a shorter grip, barrel and frame, and reduced magazine capacity. A new, two-piece wrap-around grip panel construction was used to conceal the exposed back strap. The smaller size made it more concealable than the original PP and hence better suited to plainclothes or undercover work. It was released in 1930.
