I can't see any rust damage to take off. It's had a pretty pampered life.
Anyway, I talked to the "Head Man In Charge" of the IDPA club yesterday after I had ordered the upgrade parts from the gunshop/indoor range. It seems the owner may feel he's not been supported as much as he should by the shooters. Maybe this will help to some small degree.
I'll let you know how this turns out.
