When I did mine, I disassembled the gun and used a finish stripper to take off the gloss finish, I think it was called Strip-eze, just apply, let sit awhile then wipe off, don't sand the finish off because then your wood to metal fit of parts won't match.It took a couple of coats to get all the finish off,I then stained it the color I wanted, vary lightly sanded the raised grain and applied a tru oil finish. As for stripping off the bluing on the barrel, Birshwood Casey has a bluing finish remover and degreaser, works great, vary easy to use and does a nice job, I've also heard about navel jelly, but it sorta leaves a finish like it was sand blasted from what I heard. Also heard vinegar will take off blueing, but I've only used the bluing remover degreaser. This is also a good time to add an inlay or two, or a toe plate. Kinda adds some personnel touches. good luck & take your time.
