I haven't bought a pistol in a couple years now but found a custom pistol online for a good deal, something none of my local dealers could get. I make the deal with the gun owner, sent the money and he takes it to his FFL to ship. In the meantime I call my FFL and make sure he will accept the transfer at which time he emails me his FFL license to send to the seller's FFL. I send the FFL license to his dealer who refuses to accept the copy of the license from me. This is a first for me, I have sent my FFL's license to dealers and other FFL's without a problem many times. The sellers FFL said that the copy of the license has to come to him directly from my FFL and not through me. In the past I have had a receiving FFL demand that the license was faxed to them but had no problem with me faxing it. I forwarded the email directly from my FFL and he can see in the email string that my FFL sent me the copy of the license. Is this FFL being a little unreasonable or is this common?
