This is for a handgun.
This is what UPS has on their website:
Handguns, as defined by the Acts, will only be accepted for transportation in
UPS Next Day Air Services, but will not be accepted for transportation via UPS Letter Centers, Internet
Shipping, or in response to a request for a One-Time Pickup or for On-Call Pickup Service. Firearms, including
handguns, will not be accepted when presented for shipment at a UPS Authorized Shipping Outlet or a UPS
Commercial Counter.
Here is what Fedex says:
Firearms must be shipped via FedEx Priority Overnight and may not be sent C.O.D. Upon presenting the package for shipment, the shipper is required to inform FedEx that the package contains a firearm. Firearms may not be shipped in one complete piece. When tendered for shipment, the firearm must be rendered inoperable, either by removing the firing pin in the gun and disconnecting the barrel, or by some other means so the package does not contain a completely assembled, usable weapon. The outside of the package should bear no label, marking, or other written notice that a firearm is contained within. This includes the abbreviation of the name of the shipper or recipient if the name would clearly indicate that the package could contain a firearm.
How the heck are you supposed to send a firearm back to the manufacture when you can't write the manufactures name on the box?
