That gun thing really happens. There was a reddit thread on checking a starter pistol. Apparently when you declare a firearm you go to a special TSA station for inspection and then you can use a giant padlock to keep the case secure. Supposedly, inspected fire arms cannot be opened again and are kept track of very well.
