The Gerät Potsdam was the straight copy of the gun while the MP3008 rather took elements from the Sten while keeping the final design more similar to the MP 40. The design was both copied entirely and great influence of some German arms projects.

Also, the Spz-kr assault rifle uses the receiver and components from the Sten Mk II. Some MkIIs were fitted with a wooden stock as this part was desirable and interchangeable with the Mk V. Sten Mk II's in German possession were designated Maschinenpistole 749(e) or MP.749(e). 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. 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. 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. A removable barrel was now provided which projected 3 inches (76 mm) beyond the barrel sleeve. The flash eliminator and the folding handle (the grip) of the Mk I was eliminated. It was a much rougher weapon than the Mk I. The Mark II was the most common variant, with two million units produced. In order to rapidly equip a sufficient fighting force to counter the Axis threat, the Royal Small Arms Factory, Enfield, was commissioned to produce an alternative.

The American entry into the war at the end of 1941 placed an even bigger demand on the facilities making Thompsons. Prior to 1941 (and even later) the British were purchasing all the Thompson submachine guns they could from the United States, but these did not begin to meet demand. The army was forced to replace weapons lost during the evacuation from Dunkirk while expanding at the same time. The Sten emerged while Britain was engaged in the Battle of Britain, facing invasion by Germany. Diverse Underground Resistance Group Fabrieken. Long Branch Canada (plus numerous sub-contractors making individual parts).
