Who make a 12g pump out of stainless???
Wasn't the Marine Magnum 870 stainless?
Seems like nobody's answered the basic question here:
Mainly, marine shotguns seem to be geared toward line-launching applications. Certainly they'd be effective close inboard for water-borne creature defense (jaws, etc.) but the Mossberg line caters extensively to line-launching for rescue, both WITH the boat and OF the boat.
I had a Mossberg catalog as a kid, and was amazed at the different line-launching paraphernalia they had listed in that publication. Quite neat stuff, some of it.
