The Interdynamic MP-9 is a blowback-operated fully automatic 9 mm caliber firearm classified by BATF as a submachine gun. It is made of inexpensive molded polymer and stamped steel parts. 10 20 32 36 and 50 round magazines are available. The MP-9 came from a design that a Swedish company Interdynamic AB of Stockholm had for a cheap submachine gun for military applications. Interdynamic was unable to drum up any interest among governments and the subgun never entered production in Sweden.
