Stainless is called stainless for a reason. It will stain less. It is not called stainproof. The closest to stainproof steel I've seen is Tennifer treated carbon steel. I have cleaned rust from stainless gun barrels that someone thought needed no protection. When Glock choose Tennifer treated carbon steel, they ran test against all sorts of steels treated, and stainless steels, one test involved a year under saltwater. No stainless made it. Even the tennifer treated carbon steel showed some rust, but the part still showed it had integrity. I have a stainless Luger, but I'm not about to let sit with no protection on the surface...
