My go to “bear gun” is a Winchester 12ga, pump with a short (18”) barrel and a pistol grip instead of a regular stock. The idea is to keep it short and reasonably portable so it is easy to bring along on outings. I’ve been dragging this gun around for nearly 2 decades. The problem is corrosion resistance. It’s a blued barrel and has more than a few rust spots because it rains up here and the gun doesn’t always get the attention it should in wet environments.
I’d like to replace it with a “marine defender” type shotgun. Short barrels, longer magazines, and corrosion resistant. The choices seem to be:
Winchester Super X Marine Defender: Chrome barrel, aluminum alloy receiver.
Mossberg 500 Mariner: Marinecote barrel, anodized aluminum receiver.
Remingtion 870 Marine Magnum: Electroless nickel plated barrel and receiver.
I’m not too particular about brands or looks. Price is a factor but not the primary one. I just want something that can deal with the weather with little care from me. Any opinions on which of these guns is most resistant to corrosion? I have a stainless 30-06 that is my main hunting rifle and I love the fact that it can be wet for a week without issues. They don’t seem to make stainless shotguns however.
