Reblue and go for new!
Here's my thoughts...In CAS we are playing like it was 100 years ago, right. If you think about it, 100 years ago, those guns would likely look new.
In my experience, it seems that the shotgun takes the most beating of the three. I happen to have a refinished 97 and one a little more "rustic". I often decide which one to use based on how I have to stage it or restage it ofter use. ...I usually use the beater. I also have a double Stoeger in 20 gauge that I get a kick out of shooting once in a while.
