I love mine, but I didn't get it for the supposed resistance to weather related issues....I've hunted on the wet side of Washington state all my life and have never had a problem with rust or corrosion on any blued firearm using a good protective gun oil. I've read of some that use a good wax with excellent results, too. In a marine environment, a stainless firearm should have some advantages, but for us land dwellers, in my opinion, I don't think they're necessary....but they sure look cool!!! Unfortunately, on a Handi, the parts that need to be SS are blued, all the internals are the same including the trigger, hammer and sometimes the barrel release, seen it both ways.
I installed a brushed steel trigger guard and spacer on my '06 to enhance the appearance of being all SS. :wink:
