Some people shouldn't possess firearms!
So here is the story I purchased a pistol from a private individual on GB. Communication is excellent and all the searches make it look like a legitimate deal. I send the USPS MO for the purchase price and shipping the day after winning the auction and the buyer receives it on Wednesday. I explain to him that my FFL is closed on Mondays and would like it shipped Wednesday or Thursday so it's not stuck sitting on the UPS truck, I paid for 2 day shipping so that should've been a problem. Wednesday night rolls around and I haven't received a tracking number, so I sent an email to him. Thursday afternoon I receive a email saying that my MO was investigated by the USPS for counterfeiting but all was OK and he had shipped on Thursday. I tell him thats OK and I waited for the tracking number. It shows up and shows it was sent ground and would be at my FFL on Tuesday.
I send another email and ask him why he shipped ground and not 2 day like I paid for. His response was it was too expensive to get it there by Saturday. I then wonder how he shipped it ground since UPS requires firearms to be sent 2 day. First strike against him, then I think to myself if he shipped it ground he didn't declare it as a firearm so second strike against him. I watch the tracking as it cruises around the country in a way that only UPS understands. It finally shows up today and I get an email from the seller that my FFL had contacted him and told him that the gun was loaded including one in the chamber. WOW STRIKE THREE, FOUR and FIVE. Luckily my FFL vented their anger in a phone call to him and didn't report the incident.
I was able to pick up the pistol and I'm really glad no one was hurt or worse. By the way the pistol was a SA/DA so it could have ended very badly. Off the top of my head the guy committed at least one felony and violated at least three UPS regs besides the fact of beeing a complete dipshit. I haven't left feedback for him yet as there were a couple of small issues with the gun itself and I'm also waiting to see how he handles those issues.
