I would just add that there are various "grades' of stainless steel, for example, 300 series is non-magnetic and what most of us think of when we think of stainless...but many firearms manufacturers are using 400 series stainless which IS magnetic...test yours and see! The difference between the two grades mainly is the quantity of nickel and chromium...316L stainless is great for outdoor use, and has the most chromium and nickel content, 304 has less chrome and nickel but still is non magnetic, just not as resistant to rust outside, 301 stainless has the minimum content of chrome and nickel to still be non-magnetic,but keep in mind that STAIN-LESS steels can and do rust or "stain", just put your stainless steel revolver outside near the ocean for a couple of hours and you will see light rust begin to appear if it is unprotected with a thin coating of oil. The cost of Nickel and Chromium is expensive and why stainless is more expensive than non-stainless steels.
I just showed a relative of mine that a magnet would attach to his expensive stainless steel custom 1911 and he was shocked :shock: to say the least, the grade of stainless does not affect strength...etc but does not guarantee that your firearm is impervious to rust, just more resistant to rust than carbon steel.....hope this helps....just take care of your guns and they will take care of you...
