Before World War II, 500 M1911s were produced under license by the Norwegian arms factory "Kongsberg Vaapenfabrikk", as "Automatisk Pistol Model 1912". Then, production moved to a modified version designated "Pistol Model 1914" and unofficially known as "Kongsberg Colt". The Pistol M/1914 is noted for its unusual extended slide stop which was specified by Norwegian ordnance authorities. 22,000 were produced between 1914 and 1940 but production continued after the German occupation of Norway in 1940 and 10,000 were produced for the German armed forces as "Pistole 657 (n)".
