While I agree with 45Gunner about not trusting a bureaucracy to keep records accurately (especially if said records help you but not them), but I feel compelled to point out that the original question in THIS thread was about FFLs. The issue of paperwork for direct, face-to-face sales in states that allow such is always contentious. 45Gunner may want his CYA form if he sells a firearm privately (and I understand the reasons for it), but the flip side is that if I am a buyer and if I wanted a paper trail, I'd be buying from an FFL in the first place. If I were dealing with a private seller and he asked me to provide a bunch of personal information and to sign a form, the deal would end right there.
Of course, it's easy for me to hold to principle, because my state doesn't allow private transfers without paperwork. So perhaps it's because I am already preconditioned to sell through an FFL, but I think I'd sell through an FFL even if it were NOT required, because then it isn't my responsibility to decide whether or not the buyer is prohibited.
