I sure hope you are aware of the "Damage" the set screws used to secure the shoe to the trigger do to the Case Hardening or "Flash Chrome" on your trigger. Circles where they tightened on the trigger are permanent unless you can have the original finish redone. A SUGGESTION: Please find a "Target Trigger" instead if your revolver has any collector value.
