From what I can see in the pictures I think the side plate shows signs of buffing around the edges. That would indicate to me a re-plating job. There are numerous plating finishes and several look like stainless. With that PPC bull barrel on it I would bet it was stainless barrel, and they finished the blued gun to match the barrel. Should be a good shooter, most of the PPC guns would hold a > 3" group at 50 yards.
