That is correct,only hubs of both common carriers can be used to ship guns-there may be a way to have Fed Ex p/u a gun at a business account.And you were right,GLS to insist it be declared a gun-not only for insurance,its a federal law !
May a nonlicensee ship a firearm by common or contract carrier?
A nonlicensee may ship a firearm by a common or contract carrier to a resident of his or her own State or to a licensee in any State. A common or contract carrier must be used to ship a handgun. In addition, Federal law requires that the carrier be notified that the shipment contains a firearm and prohibits common or contract carriers from requiring or causing any label to be placed on any package indicating that it contains a firearm.
My USPS Priority-handgun shipped out Monday, arrived without an issue,and the tracking was fine.Certainly not perfect but its my only choice as both hubs are an hr away.
