About 6 weeks ago, if some remember, I had concerns about my GP100. I posted pics of what I called the forcing cone, but it certainly did not look anything like the OP's pic. Ruder did ask to see it and I sent it to them, postage paid and had it back in about a week. It is obvious that the forcing cone looks different than before I sent it to them, almost beveled slightly. All it said on the paperwork was "barrel repaired, safety check performed". No detained info.
Something is different, I can see it. Took it out not long ago and it shoots just fine.
I have had 3 encounters with Ruger customer service....all very positive.
