I have used Midwest Gun Works to re-blue a few long guns and they did an absolutely perfect high quality job. One gun was a Browning T Bolt that was severely damaged by "Salt-wood" and the other was a Marlin from the 40's which was really in need of a new finish. I do not know of they do hand guns, but you might want to give them a call and find out. I'd highly recommend them! By the way the entire process from me to them and back took less than 3 months - unlike some refinishers that have more than 12 month wait times.
I TRIED to use Ford's once and made repeated attempts to contact them for pricing, instructions for shipping and lead times but was unable to get them to return any of my calls. Guess they have so much business they didn't really care. While I have only heard good things about their work, I won't deal with a Company that treats me like I am an annoyance or that they are doing me a favor by responding to my inquires - which they NEVER did! There ARE other Company's out there doing fine work that treat their costumer's with respect and professionalism so there actually IS A CHOICE.
For Colt's - believe it or not Colt STILL does a stellar royal blue and case color job - actually they do it better than ever! I do not like Smiths current re-bluing process and agree with Laketime's post above.
