I totally disagree with your statements - as does the ATF. I hold an FFL-03 (collector of Curio and Relics) license and there are laws that allow me to Buy AND SELL firearms. I am not allowed to have access to the Federal background check and so obviously cannot run a check. Well you say I deal in old guns, right? Almost all SKS rifles in unmodified condition are Relics, many 9mm, 38 spl, 357mag handguns. Swiss K31, Garands, Mosin Nagants etc are all "curios and Relics". Almost all Firearms made before 1962 (they must have been orginally issued as non-select fire or full Automatic to qualify) and even some Full AUTO Machine gun are considered Curio and Relics (although I can't afford the $$$). I am allowed to buy and SELL to enhance my Collection as long as I do not receive a "substantial" portion of my income from this practice. Truthfully I have only traded one gun at a gun show. This was a Colt 22 cal AR that I traded for a Garand with some cash. I have given a few guns to family members as gifts (all hold LTCH's). I normally don't sell any of my collection - haven't sold one since I obtained my license last year, but if the right price was offered and I could purchase another gun I want - I might. I honestly believe VERY few (and they would be very dumb) felons would attend a GS to purchase a firearm. Most are not that stupid, I feel sure most gun shows have at least one, if not more, ATF agents in attendance as well as LEO's. Felons are also aware of this and certainly have other avenues to purchase or steal weapons without the attendant risk of being arrested at a GS. I'm also sure a few new gun buyers at gun shows may be rejected by the background check for something in their past that they didn't know disqualified them - maybe a fight with their wife 20 years ago they were "charged" with domestic abuse.. Which will disqualify them.Well, to me, any transaction where a firearm is sold or traded can be deemed "firearms dealing". Does not matter if it is one time or many, you would still be dealing in firearms. I dont believe an FFL is needed, however I do believe caution and a (nics?) check be done so as not to sell, trade, to a felon. Not sure if its called "nics" or what.
