Having lived in Hawaii and seeing the affects of carrying a blued revolver (uniform duty and even under a light shirt) at belly level. Truthfully, I didn't wipe down my duty revolver with an oily rag on a daily basis. BUT, whatever. Rust is real.

Bottom line: I prefer SS. Not saying that SS it's totally rust free and checking for rust under the grips is still recommended.
