I've got two names for you. One in Mississippi, Robert "Bob" Jones who is probably the best and most respected one around. His guns have won the last 10 or 11 National Championships. He builds guns for 9 time national champion Phillip Hemphill. He also builds guns for the border patrol team, who are probably the best team in america right now. I dropped my phone in the lake and can't find Bob's card. If you can get the Mississippi Law Enforcement Training Academy in Pearl MS, Phillip or Dan can put you in touch with Bob. Bob will build you a gun whose function will be beyond reproach with your frame for $1,000.
The other gunsmith is from Louisiana, Jim Clark, of "Clark Custom Guns" in Shreveport LA. They build and work on guns for Jerry Miculek. If you provide him a frame he will build you a ppc gun for about $1100.
Both run respected shops and you will be pleased with either.
