When you eject a mis-fire is there a solid dent in the rim of the casing or just a light dent or no hit? I have many 9422's and never had an issue. Well I take that back. I picked up a very nice conditioned example really cheap at a gun show. It wouldn't cycle or fire well. I opened it up and someone had either spilled beer or pop in it. It was a gummy mess. Took a couple hours to clean up and it worked perfectly.
