Thanks for the responses. I'll need to get some more info from my friend and contact Ruger for him. I think his pistol is 5-6 years old. He told me that it was stored in a "cheap" cloth pistol case that's padded with a zipper. It was stored in a closet that developed a leak, and as you can guess, right over his ruger. There is some rust, not much. But he said there's alot of mold and mildew on it and it smells "funky" too. He's finally sold on the idea of getting a safe for his firearms.
