I mentioned in the shotgun section that my wife's uncle is giving me a shotgun, one of several he has inherited. I know it has to go through an FFL, but does he need to send it through one to mine? Or just send it to mine. And my next question, who is best to use for doing this? FedEx, UPS, USPS? Its going from Colorado to Nevada, I am taking care of the shipping. Any recommendations?
