English: Beretta introduced a series of prototypes of the Beretta submachine gun before reaching the finished model of the Beretta Model 12. Models 6 through to 11 were all very similar and were designed and tested during the 1950's, leading up to the perfect, Model 12. The small ammunition isn't very effective at a distance but in a short range shoot-out, it can be devastating.
