A while back I had sent my Ruger SR45 back to Ruger for light primer strikes but........... when I got it back it was worse than when I sent it in,the take down pin and a roll pin were literally falling out unassisted so I sent it back for a second time.I took a few months to get to the range to test it out,went to a newly opened indoor range here and put about 130-140 rounds down range with only one problem.One of my mags wasn't allowing the slide to lock back after the last round was fired but since then Ruger has replaced it.This is the only Ruger that I ever owned that gave me any problems and I've owned a few in my lifetime so I'll continue being a big Ruger fan because I love their products and if any problems arise with any of their products barring mishandleing they continue to make it right.
