I bought a G22C for my wife. Of course she complained about the recoil. So I bought a Lone Wolf 40-9 conversion barrel. We just tried it for the first time today. It would jam about three times per every magazine. We shot a couple hundred rounds. It would fire the round but wouldn't eject it. It would expand the case to where I had to remove the barrel and pry the brass out. It would always be about an eighth of an inch from being fully seated in the chamber. I was using the original spring and the 40 cal magazines. I hope someone has had a similar experience and can tell me what to do about it. Could poorly sized brass cause this to happen? I was shooting Bitterroot Valley Re-manufactured ammo. I've never had a problem with the 40 S&W that I get from them,. I have a G20 with a Lone Wolf 10-40 conversion and have never had a single problem with it. It would take any cheap crap I put through it.
