Here is the real issue I see Ex, say you do allow only pistols. Player A is inside container and is shooting out of them. Player B wants to get player A out of container so he sneaks up and draws his pistol and enters. Player A turns around and blows player B out of his shoes cause he already is on auto.

I think in order for it to be safe for both parties you need to restrict fire to semi.
