If you can make it down to Kent, Peter Dunn is at Champion Arms. One of the best 1911 gun smiths out there. I don't at all care of the shop, or management there (another story for another time)... But Peter is amazing and can do anything you want and do it perfectly. Peter was the lead designer/engineer for Detonics when they were here in Seattle and then he also was the lead designer when they moved down to Atlanta, so he knows the 1911 platform probably better than John Browning did. He does a trigger job that is out of this world, and he does it at a reasonable price.
