I'm nervous anytime anything firearm related goes to the FedEx Hub in Memphis because it is widely known that anything gun related that gets down there has a pretty good chance of being pilferedI ordered a gun once upon a time and it was overnighted by fedex.
They managed to make it take 3 days getting juggled through distribution centers, then delivered it to a non-FFL address and it was never found again.
I don't know how these companies continue to operate without people going to prison.
