It was similar to the British-made Mk. 2, component parts are interchangeable, but better production quality, smoother edges and better tolerances. The couple identical features of Canadian made STEN are using Spot welding, instead of Arc welding and the welding trace on the magazine housing is polished, like the STEN Mk.5. The total number of production was estimated to be about 150,000 STENs, and was distributed to the Canadian forces, British forces, USSR, the Republic of China, Free French forces, and others.
