I bought a used Security-Six stainless in .357, and the first time I had it at the range (I was shooting .38SPL +P ammo) the barrel broke inside of the frame. I think some previous owner put in a replacement barrel and over-tightened it, causing the barrel to break. My gunsmith sent it to Ruger for me to get a quote for fixing it, and it came back 4 weeks later with a completely new barrel, no charge, including shipping. Can't beat that!!
