[9] It features an exposed hammer, a double-action trigger mechanism,[10] a single-column magazine, and a fixed barrel that also acts as the guide rod for the recoil spring.[11] In the past, the PPK version was manufactured by Walther in its own factory in Germany, as well as under licenses by Manurhin in France; Interarms in the US, and by Smith & Wesson in the US.During World War II, they were issued to the German military (officers), including the Luftwaffe, as well as the uniformed Ordnungspolizei and plainclothes detectives of the Kriminalpolizei.[1] The PP was designed with several safety features, some of them innovative, including an automatic hammer block, a combination safety/decocker and a loaded chamber indicator.[1] 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.[15] "PPK" is an abbreviation for Polizeipistole Kriminal (literally "police pistol criminal"), referring to the Kriminalamt crime investigation office.[21][22][23] Actor Jack Lord, who played Felix Leiter in Dr. No, was presented with a gold-plated PPK with ivory handgrips, given to him by his friend Elvis Presley.[25] One of the provisions of GCA68 banned the importation of pistols and revolvers not meeting certain requirements of length, weight, and other "sporting" features into the United States.The version currently manufactured by Walther Arms in Fort Smith, Arkansas has been modified (by Smith & Wesson) by incorporating a longer grip tang (S&W calls it "extended beaver tail"),[26] better protecting the shooter from slide bite, i.e., the rearward-traveling slide's pinching the web between the index finger and thumb of the firing hand, which could be a problem with the original design for people with larger hands or an improper grip, especially when using more powerful cartridge loads.[27] In 1974, the British Royal Army Ordnance Corps purchased some thousand .22LR caliber Walther PP pistols for members of the Ulster Defence Regiment.As a result, in 1952, Walther licensed production of the PP series pistols to a French company, Manufacture de Machines du Haut-Rhin, also known as Manurhin.
