So I bought a NAA Mini Revolver from a guy today ($180 with black holster grip and pink holster grip), and when I was coming home, I noticed the front sight was missing. Not just like filed down, but there is a recess, a cavity where the sight should be. He seems like a nice guy and I don't think he did it intentionally, but I don't know if I would have paid that price knowing the sight was missing (he actually turned down a gun for trade because it didn't have original grips). So what would you do? Ask for some of the money back? Try to get the sight replaced?
Here's a picture of what I'm talking about:
