I have been getting more and more stovepipe type jams with my Ruger Mark II pistol in the last few months. I have tried quite a few different types of ammo both standard and high velocitylately to try to solve the problem without success. By frequent jams I mean one or two out of every 10 rounds. Even the high velocity stuff is jamming now. The extracted round will stovepipe and a fresh round will be stripped and jammed halfway into the chamber which ties the pistol up. While doing a careful cleaning I noticed the ejector has what appears to be a lot of play in it, both side to side and up and down. Also the ejector looks like it is angled downward instead of being parallel with the bolt tunnel. I never paid much attention to this part before and I do not know whether this is normal or not. It looks like the ejector is crimped down on a large pin inside the bolt tunnel and it doesn't look like something you should go after without a special tool. Any comments/suggestions will be appreciated.
