I Had some trouble trying to ship a couple black powder pistols thru UPS, was told they had to go to a FFL, and by Next Day Air. Contacted UPS Customer Service, and found that was incorrect. Took copy of UPS Customer Service reply with to my local UPS and told them they had better read the reply from Customer Service. The UPS manager wasn't very happy, about having to follow UPS procedures. But I suspect he did'nt want me to re-contact UPS. I believe some of the UPS employees either just don't know UPS own rules, or they are part of the Anti-gun crowd and want to play games.......
