The Walther PP (police pistol) series pistols are blowback-operated semi-automatic pistols.
They feature an exposed hammer, a traditional double-action trigger mechanism, a single-column magazine, and a fixed barrel which also acts as the guide rod for the recoil spring. The series includes the Walther PP, PPK, PPK/S, and PPK/E.
The various PP series are manufactured in either Germany or the United States. Since 2002, the PPK variant is solely manufactured by Smith & Wesson in Houlton, Maine, United States; under license from Carl Walther GmbH Sportwaffen. In the past, this particular model has been manufactured by Carl Walther in its own factory in Germany, as well as under licenses by Manurhin in Alsace, France, and by Interarms in Alexandria, Virginia.
Originally built in 1929, the Walther PPK remains a popular pistol used today for concealed carry, V.I.P. protection, MI5, European and American police. It has also been a popular display pistol to give as a gift to American and British military officers.
