There are a few good choices in the NoVA area. The aforementioned Robb Jensen is top notch (though I know him more for AR15 work). Jim Carroll (formerly of SpecDive) is at C&R Firearms just down the street from Elite Shooting Sports and is known for 1911 work. I believe Everett Oesterling is with Sterling Arsenal now; he performed some trigger work on one of my 1911s a few years back.
