I've dealt with them before, and since I actually live near them I just can drive to their shop.
The good:
*They do EXCELLENT work on 1911s.
*Quality is top notch, they can turn a mediocre out of the box pistol into a wonderful jem!
*They do very good trigger work on Sigs, BHP's, and they do fine work on CCW guns (Kahrs, NAA Gaurdian, etc).
*Very good work on Ruger & Smith and Wesson revolvers (I'm not sure they still work on the revolvers though)?
The bad:
*They work on very few types of guns (if you don't have a gun they work on, your SOL).
*Very high prices, IMO.
*Turn around time is VERY POOR IMO (they've taken months to do even minor work for me in the past).
*Customer service is subpar--they act resentful when you call them and ask the status of your job order.
Overall: They do very good work, but you have to live with their weak areas if you plan to do business with them. I'd recommend them, with the condition that the bad areas do not bother you much.
