ITM Model 4

The ITM Model 4 is a submachine gun developed by ITM Tool & Die of Ohio for urban warfare operations.
Development
This weapon was designed by Ion Mihaita in 1989 for use by military and police forces in close combat, particularly in urban combat. The weapon has a secondary use as a longer-ranged weapon for precise shots. The weapon has two barrels, two receivers, and two magazine inserts to feed what are essentially two weapons melded into one. The user may fire one or both barrels, with both on automatic, both on semi automatic, or one on automatic and one on semi. Two selector levers are provided to enable this. The front magazine feeds the lower barrel, and the rear magazine feeds the upper barrel.
