I've been wondering, when a manufacturer chooses to highlight a stainless gun with black parts, are they blackened stainless, or blued? I would think that a person buying a stainless gun would do so for the rust resistant properties, but any blued parts might start showing rust and look hideous too soon. I would prefer an all stainless gun except for blackened sights (for the purpose of being able to define them better). They could be blackened stainless if possible. IF they use blued parts, I think they are doing a disservice to the buyer.
