Really cool looking! I've always liked the Mariner (for the rust protection). The closest I've come though, is a 500 with a heavy coat of flat black hi-temp spray paint. For my shotgun home defender (safely & securely stored, as per Maryland Law, which I can access in a couple minutes ), I prefer the John Mason/Black Warrior hand grip. It is wider than many others, but most of all, it attaches almost 90 degrees to the axis of the barrel. That pretty much forces the shooter to shoot from eye level or the the high-ready (and lessens the risk of a battered/dislocated thumb).
From seeing yours, I think I'll be keeping an eye out for a Mariner.
