It just keeps getting worse. After replacing the faulty slide stop on my RIA Tac II Ultra with a Wilson Combat bulletproof slide stop, I found that cured my premature slide stop issues. Now today at the range, I put 100 rounds of Magtech 230 grain ball through the gun. On the last (and only last) round of every single magazine (using Wilson Combat ETM mags), I had awful failures to eject. On every last shot, the spent case would wedge itself like this: So after firing all the rounds, I noticed that the feed lips on my magazines didn't look right: So now my awesome tactical Rock Island 1911 won't eject the last casing and jams up horribly, AND it ruined both of the feed lips on my expensive Wilson Combat magazines. The gun ran fine on every single round except the last round in each mag. I'm about to drop this dud, sell it for a loss. What should I do?? Please help!
