Jseime, you named a few reasons why I prefer the 500, but Im not looking for a 500 vs 870 thread, Ive seen more than enough of those on here. Im only interested in their marine counter parts.
Interesting that the 870 treats the internal parts. That alone could sway my decision. I dont much care about black, but I deffinantly do not want a real shiny gun in the bright Florida sunshine.
Ideally, Id like to keep it in a boat where it would be exposed to salt water and such, and id like it to be protected best it can be before it gets a chance to be cleaned.
