I'm not sure this is the right category for this question, but here goes, anyway.

I'm looking at a pistol. I know it's either satin nickel or electroless nickel. Are they the same thing, just different names for the same process? I don't know how to visually tell the difference. All I know is that it isn't shiny nickel.

And what about finish durability? Does either finish show scratches and random handling marks worse than the other...or worse than a blued gun or a stainless gun.

I guess that's more than one question, isn't it? Anyway, any help will be appreciated.
