Walther PPK (Polizeipistole Kurz – Police pistol ‘short’) is a shortened version of the Walther PP (Polizeipistole) and differs from it in size (shorter barrel and grip) and magazine size. The Walther PPK was first presented in 1931; it quickly became very popular among European police agencies and civilian shooters since the gun was reliable and easy to conceal, but of moderate power. During the Second World War the guns were issued to German military police personnel, high military officers and other military personnel.
