Hate to seem ignorant, but I need to get straight on something so I don't run afoul of any federal laws at the gunshow. Thanks in advance for any guidance shared here. Gunshow sales/trades involving any dealer must be done with the background check and fee paid to be legal. Right so far? What about private party to private party? And is it okay to solicit for that? I often see people at gunshows with signs on their backpacks explaining what they have for sale or what they want to buy. Since, as an Oregonian, I can do private to private sales/trades most anywhere in the state, here's where it gets murky for me... If 2 private people at a gunshow walk outside to a car to do a deal is it legal? If they simply exchange contact info at the show and arrange a future meeting to sell/trade somewhere else, is that legal? I'd basically like to attend a gunshow and "advertise" a pistol for sale that won't even be with me. I'm also looking for a .44 mag lever, private to private. Is that okay, or does ATF have a problem with me trolling for private contacts on their turf? Any hidden traps or scams I should look out for beyond what common sense and reasonable instincts might dictate? Appreciate advice from those who know.
