I don't know if this was the case with the Stampede but Uberti has long offered a faux "charcoal blue" finish that is actually nitre blue. Which is very blue and very fragile. Real charcoal blue is much darker and is one of the most durable blued finishes. It's also much more expensive.A lot of the early Berettas had really blue (maybe too thin) bluing.
Does Beretta even make their own SA revolvers? I think I read somewhere they are made by another Italian company for them, I think it was Pedersoli but it might have been Uberti too. I might be wrong because I read about it a long time ago.I don't know if this was the case with the Stampede but Uberti has long offered a faux "charcoal blue" finish that is actually nitre blue.
