The Sjögren Inertia Shotgun was a 12 gauge semi-automatic shotgun designed by the Swedish inventor Carl Axel Theodor Sjögren, initially manufactured by AB Svenska Vapen- och Ammunitionsfabriken in Sweden and then by Håndvåbenværkstederne Kjöbenhavn in Denmark.[1][2] It used an inertia system later revived by the Italian firm Benelli and today widely used in shotguns. It saw very limited service in World War I by both the allies and the central powers, and service with other armies and resistance groups of the interwar period and World War II. A small number of semi-automatic military rifles in 7.63mm calibre based on the Swedish mauser using the Sjögren system, fed from internal five round magazines, were also built, and tested by potential buyers, but found no market.[1]
