Almost killed him, gun jammed. Very bad. Better to meet ONLY where a bunch of people are around if you feel the need to sell a gun like that. Less likely to happen. Frequently too costly to go through FFL and fees too high for online. If I sell one, it's usually to a friend I know, so less chance for a shootout (lol).
Don't worry, the administration is hell bent on taking them all anyway. Looks like no one is going to stop them.
