Gang, brand new here, but I thought I'd add a couple of holster makers who do superb work that I did not see on the list. Mike "Doc" Barranti does great work. He is a Shootist and a dedicated student of all things gun and holster related; website: https://barrantileather.com
Another first-class holster maker is Von Ringler: Von's work is stunningly beautiful. His "Wyoming Combination Holster" is very popular with outdoorsmen and women from Wyoming to Alaska. https://ringlercustomleather.com
I'll warn you, however, both of these gentlemen are backordered for custom work.
I need to find one on the list that will take on two 1911 projects that another gunsmith on the list started but appears to have no desire to finish. I know that is going to be a challenge because a lot of smiths don't want to work on something that someone else has messed with. I don't blame them since it's no different turning wrenches and getting someone elses half finished bullshit.
I know that Joe Chambers has fixed some less than optimal work done by other smiths - he's worth giving a call. He's very detail oriented and stubborn (in a good way) about getting things right. You may have a long wait ahead, though. I'm not sure what his backlog is like these days.
Wilson Combat! I worked with them and several of them have never had but one job from HS on and they are still at that one job they had when out of Machinists school in their late teens or early 20's. Several have been there 30 plus years and the volume of guns they have laid hands on and hand checkered from the start is staggering!
I think Brandan Bunker definitely earns a spot on the list. The precision of his builds takes to the .0001 what other smiths take to the .001, not to mention the option of PVD coatings that look like traditional bluing.
