Me, too.My SR9 had just a touch of peening on the edge nearest the barrel, not on the end with the two lugs, after the first outing. It was very minor, and I just filed it off when I noticed it. It never peened any more after that. My SR9c has had no signs of peening at all.
What a wonderful world it would be if everyone I dealt with had the quality of both product and SERVICE that Ruger consistently provides.Got my gun back yesterday. They replaced the barrel, striker, and magazine disconnect.
They were very quick, quite happy with the service.
