Part of the reason I try to buy local, is BECAUSE I don't have to put that gun on the confiscation list.
(ya right, I forgot, there is no list. [/sarcasm])

The seller sets the rules for his sale, and I have clicked OFF of a listing, because of the seller's rules. Most of the time a handshake will do. Occasionally I have provided, or wanted, a bill of sale, which I don't have a problem with. Some are satisfied if they can see your CCW. (if you have one) But to require a 4473 and a background check, for a face to face private sale??? I don't think so. There will be another gun along shortly.
