From the best I can tell, the only way to ship handguns is via Fedex or UPS, and both require next-day services. Which is really expensive. ATF regulations do not stipulate how you send them I don't think, just that you use a contract carrier (not USPS). Soo, my understanding is if I am selling a handgun, I have to spend the $$ and send next day? Right, wrong, otherwise?? The reason I'm inquiring is over the years I've purchased many from private parties and some, (most?) of them do not ship next day. Are the breaking the law? Or is this just a regulation they're breaking between shipper and the carrier, so it's not "illegal" ?? If you were to sell a handgun to a private party and have to ship, how do you get it to their FFL?
