This is a later WWII production version of the original Beretta Model 38A. Basically this version did away with the perforated barrel jacket and instead had a smooth slightly heavier barrel of approximately 11.0 inches in length with an integral muzzle break on the end of the barrel. They used the simple stamped sheet metal receiver with a welded on magazine and trigger housings with fixed front and rear sight. It has a machined bolt and barrel with the barrel having a threaded collar that was held in place with a single cross-pin, all very similar in design concept to the MP40 and STEN, submachine guns. One unique aspect of this weapons is that it has a double trigger assembly; with the front trigger firing the weapon in a single shot mode with the rear trigger firing it in a fully automatic mode. It has an Italian walnut stock and comes complete with one 20 round stick magazine. This weapon is currently registered with the BATF as a class III/NFA SMG, however it has been deactivated by brazing a plug in the chamber area of the barrel.
