The Danuvia submachine gun, or the Király Géppisztoly, is a Hungarian submachine gun.


Designed in the late 1930s, the weapon was issued to Hungarian army troops in 1939. The Danuvia submachine gun was similar to a carbine, due to its size. While inspired by the Beretta Model 38, the Danuvia used a slightly more powerful round. Like the Beretta design, the magazine can be folded forward into a recess in the stock where it can be stowed away for easier storage.

Design DetailsEdit

The Danuvia uses lever-delayed blowback, using a patented two-part delayed blowback bolt. The fire selector is a circular cap on the rear of the receiver. The ejection port and the cocking handle are on the right of the receiver.


The Danuvia was originally designed as the 39.M; it was later modernized as the 43.M, with a distinctive curved magazine and a shortened barrel. The 39.M had a second variant which was the 39.M/A, featuring a folding wooden stock.
