You're an attorney? Have you even read Abramski? That wasn't a "gift" situation in any way shape or form. Abramski bought the gun, on behalf of his uncle, using money his uncle gave him, in order to get a discount the uncle didn't qualify for.

What part of that fact set applies to me, buying a gun for myself, to give as a gift, using my own money, with no renumeration nor quid pro quo from the giftee?

The 4473 asks if the person making the purchase is the intended -buyer-, in Abramski he was not. Note that per ATF's own FAQ gift purchases are explicitly legal, even for juveniles who could not purchase the firearm themselves.

Yes. However, persons less than 18 years of age may only receive and possess handguns with the written permission of a parent or guardian for limited purposes, e.g., employment, ranching, farming, target practice or hunting.
