Welcome to the forum.
M17s are very popular around but rebluing is not. Most will tell you to keep it like it is and enjoy it as a shooter because rebluing generally hurts the value of the gun and you will not get your money back if you ever sale it.
There are some here that have reblued guns and most the ones I've seen were done by S&W. They looked very good. Fords in Florida has a good reputation for gun finishes and you can check their website to see some examples. I'm sure there is others that can recommended.
Why do you want to reblue it? If you can show us a picture of the gun we'd have a better idea of if it's needed.
my friend dropped it and put a scratch in it...polished scratch out and removed the bluing...its a sad situation...no will want it in its condition anyway..what to do...cant post pics...thanks...
Sell it to your friend and buy your self another. Make sure you get enough out of your old one to buy another one you like. Your friend will have learned a lesson and will be more careful next time. Don
I can't see refinishing the revolver unless you plan on keeping it for a very long time because between the shipping costs both ways and the cost of the refinishing you will over $300 into the gun more then you paid for it.
However if you decide you want to anyway I would send it to S&W to refinish it because everyone up here that has sent one in has raved about the quality of their work.
A revolver has to be shipped over night by a non FFL holder which is expensive and the cheapest way if you know a friendly FFL is to have him ship it. That is because he can ship it through the post office to S&W using priority mail and that runs about half of what it costs you to ship it overnight.
If it were me I would consider the scratch to be part of the gun's character and history and keep like it is and shoot it. If you are absolutely dead set on refinishing, send it to S&W, as a factory refinish with paperwork hurts the value less than work done by others.
Before rebluing, see if you can put a matching dent in the grip frame by giving your "friend" a conk on the noggin with it.
With two areas of repair, your cost per repair will be cut in half.
