Your post doesn't provide too many details so if my assumptions are incorrect, I apologize...
What shipping a handgun it is not necessary to have an FFL holder at the sender's end. It is only necessary that the handgun be sent to an FFL holder via a common courier (e.g., FedEx, UPS and NOT US Mail).
From time to time I see threads in handgun sale forums where people incorrectly state that the seller of a handgun has to have an FFL holder send the weapon. If this is not your situation, I apologize.
