Well, I'm kinda dumb here. I've a R9 (that's how it's marked) with sights. Serial number 120, been carrying it in my pocket since I got it. Ain't got NO wear marks, looks new, it's killed some (3 or 5 snakes) and a couple of squirrels and LOT of cans and IDPA targets with the center cut out.
So, I don't think the finish has a whole lot to do with how the gun looks-as long as it is stainless steel.
