There is another option. You can take the trigger guard off and replace it with a new one. I recently bought a frame that had ALL the bluing worn off the trigger guard spur and was selling it to a friend. I did not want him to have a frame with that much blue worn off, so I replaced the trigger guard. I believe they wanted $37.00 plus shipping. I thought that inflation had got kind of steep, but it does look good. Seems like the trigger guard is a different finish. All of my frames, except for the Stainless, have worn differently on the guard than the frame part. I know that is where you touch it the most, but the entire guard on one of my frames has a hint of red in the blue. I may be a different kind of metal than the frame is. I am sure someone knows the answer to that.
If you do order, make sure you tell TC you want JUST the trigger guard and not the entire assembly. With a few punches you can take the parts off and switch them over
