mkm,
The only reason for the wry smile is because most people think I'm nuts. I carry my 1911 75% of the time and my LCP 100% of the time. These guns have both been swimming in rivers, mud holes, lakes and any other crap (crap is a very literal term for where my guns have gone) I get myself into. I ride motorcycle about 8,000 miles a year in all types of weather. These guns are in my saturated clothing for hours when I ride in the rain.
I agree with rotating the ammunition, but don't be afraid to get the guns a little wet.
