Deans,
Twice I have used Briley (3rd on that list provided by Clay) for 1911 work, and I was extremely satisfied with their work. One job was a simple grip safety fix, and the other was a $1,000 customization of an Officer's ACP. No regrets.
They are located just inside Beltway 8, just north of I-10, on a back street a couple blocks behind the Home Depot.
