Id call grumpies....google it and you will find his webste.
Talk to John at JPL Precision in Redmond. He makes competition race pistols but I am sure he could do the work you are looking for. I talked to him in length on the phone as I was looking to have him make me a custom pistol. I went another direction but he knows his stuff.
What are you looking to have done? That might determine who people send you to. Sight work should be handled by just about any competent smith. Checkering or stippling is not 1911 dependent. If you're looking for a 3 1/2 pound Bullseye trigger, I'd suggest a smith that specializes in reliable/safe trigger modifications that would pass a Nationals Bullseye Match. If you're looking for accurizing, I'd go to a Bullseye smith that can make your 1911 print 1 1/2" at 50yds. It'll cost ya though! -Steve
