I would highly recommend Alchemy! Two of their owner/founders worked for years building their craft under Les Baer and now have their own business! Wait time is okay! They rescued a thunder ranch special for me that was a mess! It is now my go to carry gun! Want to talk accurate?! Tom Rhoads
Bar-Sto Precision Machine, 29 Palms California. I personnally know Irv Stone and he has been making barrels and fitting them for over 40 years. Makes barrels for the military etc. I can't tell you the exact number of times that one of his barrels (guns) has won the Bianchi Cup, but it has been many. Good company good service and good products.
I would suggest Dave Severns of SevernsCustom.com. He has done a few guns for me with bullseye accuracy being the goal. Dave is also a moderator at the 1911 forum in the Dan Wesson sub forum. Dave often does "shoot offs" where he essentially compares various makes of 1911s by taking them apart, showing plusses and minuses and then submitting the guns to a Ransom Rest shoot off for accuracy.
One of my 1911 Dan Wesson Valors recently won a shoot off. Dave did a Barstow match barrel, trigger job and overall action tune. He is a good guy and has a great following.
Tried to get Ross to work on a 1911 for me and could not get it to work out. Have a few emails back and forth and then nothing, no contact. I am ok waiting for a job to complete, but I am not OK when guys don't communicate and I have no idea of what's going on.
