The SS is about an extra 100 bucks and to me its not worth it. I have hunted with blued guns and Matte Black guns for 50 some years in the worst of conditions and have yet to see a speck of rust on any of my guns. Wipe them clean and dry when you get a chance and don't worry about it.
I guess it all depends on where you hunt... I've hunted where $100.00 more for stainless would have been a VERY good deal...
I will NOT take the action out of the stock on a hunt unless i absolutely have to, and i've spend many days on hunts where the rust can and would get under the bbl action ect...
There are ways around it, but stainless would sure cut down on the maintance of trying to keep the rust off, on extended hunts.. That's $100.00 for me, that i would call "well spent"..... BUT, i understand not everyone uses their guns for tools and goes on extended hunts. Anyway, it's a one time expense, i'd spend it!
