I’ve got a CZ 457 and a dead air mask currently in jail. Was looking over the pictures I had taken of the two together and noticed a problem. The suppressor threads on the barrel perfectly but stops just shy of the edge of the rest of the barrel. I’m not entirely sure it is a problem but if so, what should I do about it? This is my first suppressor and I just don’t want to screw anything up. But realize I may be being paranoid about this also. I have attached some pictures of what I’m talking about. Is the gap alright?
