The latter used older more expensive methods of manufacturing, included the milling and machining of steel and the use of wood as opposed to the simpler, more modern techniques of stamping and welding.

The Madsen M1945 is a 9mm submachine gun that fires from the open bolt and only in fully automatic.

It feeds from 50-round casket-type magazines similar to the Finnish Suomi submachine gun of WW2.

The entire "slide" must be cocked back and pulled to the rear, making the submachine gun similar in function to a giant automatic pistol.
