I have a couple of Miroku-made Winchester 1892's in .357mag and they are excellent rifles - very well made. They are pricey though, relative to Marlin, Rossi, Henry and others. I don't see blued being a big negative, especially for a HD weapon, unless your home is in a high humidity environment, or near sea air, and with no central HVAC or climate control. In many homes with central heat and A/C, the indoor environment is just not really corrosive. Even if using outdoors, corrosion can be avoided with some simple basic regular/routine preventive care.
That said, if you really want stainless, your choices will be much more restrictive, and availability will also be drastically reduced (well, availability is an issue with pretty much any gun right now).
