Historical profile
Adopted by the Swiss Army during World War II as the MP43/44 to supplement the costlier Furrer MP41.
Retains the open-bolt blowback action of the original Suomi, with excellent accuracy thanks to the long barrel and heavy mass.
Remained in Swiss service into the 1960s, then stored as a war reserve.
