If you go to the Mesquite Gun Show, Ken Crawley www.crawleycustom.com
has a booth. He does very good work, and you can drop it off at one show and pick it up at the next.
Ken did a 4# 1911 trigger for me for $100. If you need parts replaced, he uses good quality stuff--Cylinder & Slide, Wilson, etc. They cost a bit, but sometimes, you really do get what you pay for.
