Many years ago I carried both a longgun and a handgun in the rain - rain that lasted all day and all night, and went on pretty much continually for 6 months at a time. No, it was not on the Ark with Noah (although I'm about old enough to have been a passenger if I could have found another animal like myself :shock
but in Vietnam.
Find a dry place. Strip the weapon down as far as you can. Wipe it dry - use compressed air if you can be sure you are blowing water out - not into - crevices & cracks. Oil it as per your regularcleaning routine. Check the next day for signs of rust. Check the day afterwards, too. If nothing shows up by then, you are good to go.
If you think it might rain on your OC parade, bring a baggie and slip the baggie over the holstered handgun. Yes, it looks stupid, but it can keep your handgun and holster dry. Just remember you are going to have a tougher time getting the thing to function if you try to shoot it while it is inside the baggie.
If you have tried to drown your weapon (ever drop a shotgun from a float blind and have to go diving for it?) you can,
only in this instance, use WD-40. Displace all the water by a liberal application. Let the weapon drain as much WD-40 as it can over the course of a few hours, then use carb cleaner to flush out every drop of WD-40. Your metal will be completely bare and need the L&P parts of CLP-like stuff.
Other folks will tell you that they use nothing but WD-40 for gun cleaning. They are the ones with shellac on the moving parts.
stay safe.
