I am new here i found a benelli at the local pawnshop and would like some more info if possible. Here is what i was told. It was a military contract overrun that was made legal for civillian ownership.It had a smooth bore short barrel roughly 15- 16'' pistol grip stock but it has a kind of flash suppresser looking piece added on to make it 18 3/4'' it's a little oversized with holes in in kinda looks ported. The guy said benelli did this so it could be sold to civillians. He also said there were only 100 of these out there. Can anyone help out with info? Thanks so much for now.
