I'm in southern Oklahoma and remember buying a Sig 230 since it was SS and wouldn't rust. Fought that sucker with an oil rag every evening and still had pits in it from rusting...
Coatings are better, I tend to carry a Glock more than anything else. My DW lightweight commander has an Alloy frame and SS slide with their Duty coat over everything but the grip screws, yep rusted one of them. Everything else I have is either SS or parkerized, no shiny blue steel for me.
