I have owned a bunch of the Ruger auto's probably ten some in 45 and several in 9 MM. I have shot thousands of rounds of all kinds and bullet shapes and reloads both cast and jacketed. I kid you not, I have yet to have a malfunction of any kind with any of them. No stove pipes, no failure to feed , No failure to eject. They just flat work all the time.. Clean, dirty, it does not seam to matter. All except one 9MM were plenty accurate for their intended purpose. Few thing I have ever tried have worked as flawlessly as the Ruger semi auto's.
I don't know what was wrong with the one 9MM but I could hit nothing with it. Ruger replaced it at no cost and no questions asked. I am a Ruger man and this is why.
