Ooo, your 870 has real nice wood! I got lucky with mine, I found a Wingmaster in a pawnshop for $325, and told the guy, hey what's with that? I can go right over to Kmart and get an 870 brand new for $189...so he said, ok 189. So I bought it, A Wingmaster! But I scarred it up hunting one day. I was making my way down a frozen creek in the rocky mountains and my feet slipped out from under me and it went flying, skating down the frozen rocks, lol. It's funny now but wasn't then.
So I bought a police trade in barrel 18" with a bead for it and had both barrels and the gun anodized gun metal grey and then I camo'd the wood instead of refinishing it. Then added the sidesaddle and extended mag and all that and it was real versatile then. and totally weatherproof with that anodizing. No wait, not anodized...something else...real tough finish. Dang I forget the name of it right now. Brain fart, lol.
Aha! I remember! it was Powdercoated gun metal grey!
