I just have the idea that if you pay the money, and buy the item...
Two issues with that.
1. You either aren't actually paying the money (someone else is actually paying and you're just going through the motions) or you are paying the money knowing you're going to be reimbursed/compensated in some way for your expense.
2. You aren't the one actually buying the item, it's someone else who is actually buying the item and they are paying for it with you just going through the motions for them.
Think of it this way: Why are you there?
If you are there because YOU want a new gun for yourself (or to give to someone else as a GIFT) then that's fine.
If you are there because someone ELSE wants a new gun and is paying you or otherwise compensating you for going through the motions for them, then that's a problem.
I understand the issue with buying something for someone who isn't legally allowed to have it...
As it currently stands, it does not matter if the person is prohibited or not. If you are there to get someone else a gun (that is not a GIFT to them) that is an offense. If you are there to get yourself a gun then you are fine.
get it, guns are a special case...
Well, sorta, but not really. There are other situations where it is illegal for someone to buy something on behalf of someone else who is not prohibited from making the purchase or possessing the item in question. For example, having someone else go through the motions to purchase a car could be illegal if it is done to circumvent the fact that the actual purchaser has bad credit. By having someone with better credit perform a straw purchase, the actual purchaser gets better financing terms and saves a lot of money. The buyer is not prohibited from possessing the car or buying the car, but what has happened is still against the law because fraud has been committed.
...there shouldn't be a "landmine" in the federal form to trap people with...
The whole FFL dealer setup is, in my opinion, an overstep by the federal government. It's a clever way to get the Feds involved in something that should be the jurisdiction of the states. So I'm not defending the idea of having the federal government involving itself in the purchase of firearms by an individual. That said, I don't think it's reasonable to characterize the "are you the actual buyer" question as a landmine.
The problem isn't the question, the problem comes when people complicate things by trying to answer what they THINK the question is or what they THINK it should be instead of just answering the question. The FFL will explain it if there are questions, but the form itself has an explanatory section that is pretty straightforward if people will just read it and do what it says.
Here's the question: (I have added some emphasis.)
Are you the actual transferee/buyer of all of the firearm(s) listed on this form and any continuation sheet(s) (ATF Form 5300.9A)?
Warning: You are not the actual transferee/buyer if you are acquiring any of the firearm(s) on behalf of another person. If you are not the actual transferee/buyer, the licensee cannot transfer any of the firearm(s) to you. Exception: If you are only picking up a repaired firearm(s) for another person, you are not required to answer 21.a. and may proceed to question 21.b.
Here's the explanatory section that applies: (I have added some emphasis.)
Question 21.a. Actual Transferee/Buyer: For purposes of this form, a person is the actual transferee/buyer if he/she is purchasing the firearm f
or him/herself or otherwise acquiring the firearm
for him/herself. (e.g., redeeming the firearm from pawn, retrieving it from consignment, firearm raffle winner). A person is also the actual transferee/buyer if he/she is legitimately purchasing the firearm
as a bona fide gift for a third party.
A gift is not bona fide if another person offered or gave the person completing this form money, service(s), or item(s) of value to acquire the firearm for him/her, or if the other person is prohibited by law from receiving or possessing the firearm.
EXAMPLES: Mr. Smith
asks Mr. Jones to purchase a firearm for Mr. Smith
(who may or may not be prohibited). Mr. Smith gives Mr. Jones the money for the firearm. Mr. Jones is NOT THE ACTUAL TRANSFEREE/BUYER of the firearm and must answer “no” to question 21.a. The licensee may not transfer the firearm to Mr. Jones. However, if Mr. Brown buys the firearm with his own money to give to Mr. Black
as a gift (with no service or tangible thing of value provided by Mr. Black), Mr. Brown is the actual transferee/buyer of the firearm and should answer “yes” to question 21.a. However, the transferor/seller may not transfer a firearm to any person he/she knows or has reasonable cause to believe is prohibited under 18 U.S.C. § 922(g), (h),
, or (x).
