Mike, good point. It isn't so much the ruining of the gun, it's how much it costs to gain little, or, in many cases, nothing. There is no real harm in professionally rust bluing the barrels on this Fox, but I think I'll leave my new Parker alone. I have about had it with barrel bluers who want to keep my guns for years to do what we used to be able to get done in weeks. My favorite Super Fox is loaded up with color but a bit light in the barrels and I think I'll leave that one alone too.
