I've had a 590a1 and when the barrel was put on and tighten down with the magazine cap the barrel still moved around. I could move it from right to left. It wasn't that loose but I would like it to be tight and not move at all. I'm pretty sure this is not how it is supposed to be because I've seen other 590a1's and they were tight with no movement. Can this be fixed or not? And if so how do I do it?
