I am trying to pin down the REQUIREMENTS for a private individual ( non-licensee ) to ship a handgun to a Licensee ( FFL holder ) within the same State. In particular NYS. I understand that some FFL holders might require certain information that they personally want to accept a handgun from an individual. I am interested in what is required by law. Both Federal and State. I know that a Non-licensee cannot ship a handgun via USPS. They must use FedEx or UPS and both require that the handgun be shipped "next day" service as well as be made known that the package contains a firearm. But, just what is required by law in regards to documentation supplied to the receiving FFL from the sending private individual?
