I have a stevens 311 that wants to open when shot. It locks up solid, I had the problem before and I replaced the top snap, now it doesn't go as far to the left as it used to, indicating the old piece was worn. However after a thousand rounds or so it has started to open again. The gun locks up like a vault yet the recoil of trap loads seems to allow the top snap to swing sideways. Sometimes it just pops a bit, othertimes it will open. I have a friend with an Ithaca double that has the same problem.
Anyone know of a solution?
