- for shotgun work D&D gun smiths ..
- for the rear sight you can check with Moe at Double action.. He might be able to put some thin shims under the rear sight to hold it in place and save the rear sight.. you can do it yourself as well.. Buy a cheap spark plug measuring shim blades from Murray's.. cut a rectangular piece and try to fit it in the rear sight groove as you re-drive the rear sight by tapping it. The thin shim should make the fit tight enough.
