I recently acquired a NOS hammer with beautiful case coloring for my 17-3 . Will the proper use of hammer shims prevent the hammer rubbing against the frame & wearing the case color off ? If so any shims in particular ?
Thanks !

The bosses at the base of the hammer stud and the on the sideplate will protect the finish on the hammer. There is no need to shim these contact points if they were properly fit by the factory in the first place.

Thanks for the confirmation!

I was going to say a properly built gun should be just fine without shims. Using them would be for special purposes, but if you have a hammer rubbing, that could be a solution.

Burrs inside the frame and side plate edges cause most of the problems with hammer and trigger scrapes. If you do end up needing shims check out triggershims.com
 
I have found that sometimes the hammer and/or trigger pins in the frame are not exactly perpendicular. Sometimes just a very small tweak in the right direction will set things right.

I have obtained hammer and endshake shims from them for S&W, Ruger, and Dan Wesson.
Also lever shims for Marlin and Winchester.
They did not have any for the Dan Wesson but myself and one other guy requested them and they made them up.
They are nice folks to work with. Kind of a mom and pop store.
 
I made a 5/16" diam. x 6" long steel bar with a hole drilled in each end on the lathe. That way the hole is exactly centered and exactly parallel to the rod. The holes are a .001 slip fit with a chamfer at the opening, one for the hammer and one for the trigger stud.

In use, if the stud is slightly off, it's easy to see once the 6" rod is on there. Then you can use the rod to gently move it in the desired direction. Also, you can use a small square from the inside of the frame to the rod, but I don't find that to be needed for myself. I don't like hammering on parts, as it can deform them and you don't have good control over how much you move them.
