I've dropped my SBE1 into Gulf Coast salty marsh muck on more than one occasion, sloshed the mud out in the salty water and shot it for the rest of the morning without a hitch. Of course I cleaned it out well and CLP'd it when I got back home several hours later. No signs of any corrosion 3 years later. These shotguns are as easy to clean as an O/U or SxS.
