I have never seen black stainless steel (?) Maybe it exists, I just haven't seen it. Is it possible this is a black chrome? I would recommend regular stainless since it doesn't show dings and scratches. Also, you can polish out any scratches and restore the finish pretty well. If you have a black gun, every scratch looks silver and shows badly. If the gun is SS, you won't be able to touch it up with gun blue liquid because SS won't blue. That said: my 92FS is the standard black finish that they call Bruniton and it has held up quite well over time.
