Fair point. In my case, I'm talking about Rugers-Specifically GP100, Security Six (stainless), Blackhawk (stainless); I'd be pretty comfortable with any of them in the field. While the GP100 is blued, I wipe it down thoroughly with a Sentry Solutions Tuff Cloth prior to excursions, which has worked well.
The Rugers seem pretty well sealed from media intrusion, relatively speaking, and field-stripping, particularly for the GP100 and Security 6, is pretty easily accomplished in the field if necessary (as long as you've got a screwdriver for the necessary screws {only the grip screw on the GP100 and Security 6} the takedown pin for the captured mainspring-the OEM grips have a slot for it, but if you've replaced the grips, you may have to find another storage location for the pin).
Best, Jon
