"he didn't want to sell a gun to a stranger without the FFL transfer paperwork.".Statistics show that classifieds with pictures sell at a greater rate than those without, FACT. There was a guy on here that had a picture but wanted to do a FFL transfer on a POW, not needed at all, but he stated Probably not going to sell real quickly. Either play the game or not, pretty simple really, it is your choice.
I can understand his POV.
Suppose he sells a weapon without a transfer that he had acquired through a dealer (4473 required). Now suppose that weapon was used in a crime and was discarded as a 'throw-away' gun. Now LEO has a weapon that is traceable back to the original owner that has no proof that his weapon had been sold. Could be a pretty sticky situation trying to prove oneself as being innocent of the crime when the weapon found at the scene was his.
