Just wondered if anyone has shot an M2. I think in full auto they would more controllable than a sub gun in 45ACP. not to mention more range. But from my very limited experiance in such thing, any thing in full auto is going to be hard to stay on target with, at leaste with out alot of practice. I have a neighbor who had one in Japan at the end of the war, but he says he hardly fired it so does not remember much about the full auto operation.
I also put in a post on the general military arm thread askin about the Reising sum gun and if anyone has had any experiances with on of those.
