My 12 ga GR3 was going a bit purple before I had the frame reblued (it's a shooter), so I wouldn't worry too much about the color.

On the other hand, I simply won't do business with ANY internet sellers who have a no return policy, unless it's a known entity (like CSMC or MGW) and I'm buying a close-out item at a blow-out price. Let this guy keep his Beretta.
