Walther PP - Walther's original factory was located in Zella-Mehlis in the state (Land) of Thuringia, in present-day eastern Germany which was occupied by the Soviet Union following World War II, Walther established a new factory in Ulm.
Production began between 1973–1974, but due to Swiss federal restrictions on firearms exportation, manufacturing had to be carried out at the MANURHIN (Manufacture de Machines du Haut Rhin) facility in Mulhouse, France.
