I'm of the general belief that a little honest wear never hurt anyone. That said most of my old originally blued steel served in law enforcement for many years and have been subsequently refinish in blue or nickel. Love them all just the same.
I missed one of these a few years ago for cheap -- but I was broke-er than cheap. Now GunJoker wants $1,000+ for beater guns that sit in the listings for months/years.
