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 semi-automatic military rifle in 7.63mm calibre, fed from an internal five round magazine, was also built, and tested by potential buyers, but found no market.[1]
