This may be more of a Mossberg question then semi-auto in general.
I just recently got a used Mossberg 5500 MkII. It is all put together and in what looks to be pretty good condition. I have a single question though. Are semi auto shotguns supposed to hold the bolt open each time if the action is worked by hand. Does the gas system have something to do with loading the next shell and closing the bolt on it? I have put shells in the gun and worked the action and the bolt holds open after I eject each shell. Now I am not sure if that is normal or not since I have always used pump and break barrel shotguns.
