THE best shooting revolver I have ever owned was a Colt Officer's Match with the King treatment, no cockeyed hammer but tuned very nicely. That was in single action...
It couldn't hold a candle to my Marvel 1911 conversion but it was a .38. I could also outshoot it with my Model 52 Smith using the same bullets. I have never taken the time with a double action revolver to get any better than military or police qualifications, it does not interest me. I have a friend that can outshoot me double action while I use single action, any revolver...he does not like serrated triggers, I almost snookered him one time.
