Can anyone recommend a top Tier shop to reblue a S&W revolver?... thank you.

Here's a good post in regards. Supposedly Ford's in Florida has gotten back to their high standards from the rough patch they hit a little while back.

Great info. Thanks

Another vote for Glenrock Blue. They've done two revolvers for me. Excellent work, reasonable prices. They did a 15-6 that was a security or LE trade in. Gun was in decent shape, no pits, or deep scratches. You must look very closely to determine it's a refinish. All markings were preserved. No dished screw holes. No rounding of the side plate edges.

I'll also add..........

Precision Bluing | America's #1 Bluing Company!

Ron's Gun Shop - New & Used Gun Sales & Service. Concealed Carry

I haven't actually seen work by Precision so my choice would be Glenrock.
