I think the gun I would most like to own and was the most fun to shoot
the M 38A Beretta submachine gun. It was about as big and heavy as the Mini-14 but fired the 9mm. It ejected to the left and had two triggers.
The best thing about it was its accuracy. Modern sub-guns try and save
weight and have folding stocks for making them compact. The 38a was
big and heavy (for a sub-gun) but thats what made it so fun.
Single shots and bursts stayed on target. The only other sub that's supposed to be this accurate is the Finnish Sumoi and I'd sure like to shoot one some day.
