All I can say about Ruger service is that somehow the entrance to the chamber of my .22 pistol was chipped after years of use and I phoned the Ruger company in Connecticut. Bill Ruger answered the phone. What do I do, I said, send it down to you? No, he said, we've a small repair department (he may have been operating out of his garage for all I know) so send it to our Peterborough office (in Ontario, Canada) and we'll make a straight exchange. Sure enough, he replaced it with a brand-new bull-barrel Mark II.
