Heavy J, Believe me when I say it's not a limp wrist problem. I bought an early KP-345PR (3 digit S/N) NIB. It had more problems than FEMA in New Orleans. There were 11 documented issues with mine involving feeding, extraction, click-no bang, sights, and magazines. Mine made a trip back to Ruger twice, mainly for the magazine disconnect issue that causes click-no bang. I repaired several things myself but Ruger wouldn't send me parts for the mag disconnect plunger. In disgust, I bought a SIG P-220 and sold the P-345.
From what I see on the other forums, Ruger has redesigned a few things and now are making the P-345 much more reliable. That said, there are still a lot of workmanship issues that raise their ugly head. Mostly rough, sharp, and galled parts. Since I sold mine, I have repaired several P-345s for other people. Most of them had the same issues as my early model. Hopefully, Ruger is cleaning up their act with this model. It's great to see someone with a P-345 that actually works.
