I spoke with the owner a Mr. Jim Wright and am awaiting more info regarding their capabilities. I was told they are the largest gun repair facility in the country with 18,000 sq. ft. dedicated to repair and restoration. They have a website
http://www.simmonsguns.com/ and there phone is 913-782-3131. All I know at this point is what I was told and have not heard good or bad any references about their work. I do know they do work for almost every major gun mfg. and have since the 50's so they should have it down pretty well by now.
