Variants
There were 3 variants of the MKMS. There was the shortened barreled MKPS which still used the overly complicated two-part delayed blowback action. This was designed for the police market. In 1935, SIG then created the MKMO and the MKPO. The MKMO had the long barrel of the MKMS but had a more conventional single-part blowback action while the MKPO had the shortened barrel as well as the single-part bolt blowback action. Both also fired from open bolt manual safety which was located on the left side of receiver.

Both MKMS and MKPS submachine guns were somewhat complicated and made to extremely high standards, so the price was high and sales were low and thus production was stopped in 1941.
