I love this 12ga. O/U but this one problem is driving me crazy. When the gun gets warm, like when shooting trap, it is very hard to break open. You have to use you knee across the action and it is not something I want to do. I have taken appart and cleaned all I could think of and it is no help. It seems as if when the gun has become hot, this problem becomes available. Obviously something is swelling that makes this problem show up. Anyone have any ideas or have had this experience themselves with these guns?
