    Reproduction B/P handguns can come from the factory with excessive clearances. Shims can tighten the action and give the gun a crisp feel.

    For my Open Tops I cut shims from copper shim stock. Brass will work well also. The hammer shim is .008" and completely eliminates hammer wiggle without any noticeable friction. The rectangular hand shim is .012" and has the effect of making the hand seem slightly longer while keeping hand in close contact with the hammer. The trigger and bolt shims on my gun are each .012". By mixing and matching trigger/bolt shim thickness you can slightly reposition the bolt to correct for Cylinder/Barrel alignment issues. Shims can also be used to eliminate loading lever rattle.

    Smokin'Joe - how did you cut your shim stock? I assume tin snips for the OD and a gasket punch for the ID, or ???


    Finally out of the attic

    NC, I drilled a hole first and then used heavy scissors to cut the OD. Then rounded off OD on a stone.
