If you're not happy now, you're never going to be happy with it so take it back to the shop/bring it up with them. They should be happy to exchange it for you. I don't think you're being unreasonable.
A dealer showed me the new gun I bought, and I was so excited I was like "Yeah, yeah, yeah, looks good," dying to take it home.
Well, I should've looked harder because it had a small nick on the barrel hood, but that is my fault for not looking it over.
Your call, I'd take it back if I were you, and not happy.
