The STEN (or Sten gun) was a family of British 9 mm submachine guns used extensively by British and Commonwealth forces throughout World War II and the Korean War. They were notable for having a simple design and very low production cost making them effective insurgency weapons for resistance groups. STEN is an acronym, from the names of the weapon's chief designers, Major Reginald V. Shepherd and Harold Turpin, and EN for Enfield. Over 4 million Stens in various versions were made in the 1940s. Action: Blowback-operated, Open bolt Rate of fire: version dependent; ~500 round/min Muzzle velocity: 365 m/s (1,198 ft/s) Effective range:100 m Feed system: 32-round detachable box magazine Sights:fixed peep rear, post front The Mark II was the most common variant, with two million units produced. It was a much rougher weapon than the Mk I. The flash eliminator and the folding handle (the grip) of the Mk I was eliminated. A removable barrel was now provided which projected 3 inches (76 mm) beyond the barrel sleeve. Also, from the operator's perspective, a special catch allowed the magazine to be slid partly out of the magazine housing and the housing rotated 90 degrees counter-clockwise, together covering the ejection opening and allowing the weapon and magazine both to lie flat on its side. The barrel sleeve was shorter and rather than having small holes on the top, it had three sets of three holes equally spaced on the shroud. To allow a soldier to hold a Sten by the hot barrel sleeve with the supporting hand, an insulating lace-on leather sleeve guard was sometimes issued. Sten Mk II's in German possession were designated MP.749(e). Some MkIIs were fitted with a wooden stock as this part was desirable and interchangeable with the Mk V. Also, the Spz-kr assault rifle uses the receiver and components from the Sten Mk II. Regular Mark II: Overall Length: 762 mm (30.0 in) Barrel Length: 197 mm (7.8 in) Weight: 3.2 kg (7.1 lb) Mark II (Canadian) - FYI (THIS STEN IS A BRITISH VERSION) During World War II a version of the Sten gun was produced at the Long Branch Arsenal in Long Branch, Ontario now part of Toronto, Ontario. This was very similar to the regular Mark II, with a different stock ('skeleton' type instead of strut type) and improved quality of manufacture. It was first used in combat in the Dieppe Raid in 1942. Mark II: Overall Length: 896 mm (35.3 in) Barrel Length: 198 mm (7.8 in) Weight: 3.8 kg (8.4 lb) Canadian infantry battalions in northwest Europe retained spare Sten guns for special missions and the Canadian Army reported a surplus of the weapons in 1944. The Sten was not used in Italy due to constraints on the shipping of ammunition; .45 ACP was already being used in that theatre by the US Army and a requirement for the 9 mm pistol round used by the Sten would have been in competition for limited shipping space.
