It finally came back, the problem was just poor quality control from the Performance Shop! Now fixed and it shot quite well with CCI Minimags.

Yes, I know most recommend CCI SV but I have shot Minimages for forty some years and like them. My last 41 went through 10's of thousands of them and it was still working well when I got rid of it (mistake).

This repair did not cost me anything but time and that's damn expensive at my age. I wish I would have purchased and older used model instead of going for the Performance model. Modern S&W is not worth the money in my opinion, and "Performance Center" is truly a joke.

I have started looking for a decent 22 lr pistol. I don't want to deal with S&W ever again.
