What I've never understood is this:
At it's first sale at a dealer, a handgun must enter the stream of commerce through an FFL.
So who's the moron who registers the gun in his name and then later sells it privately without an official transfer?
Gun gets used in a crime, who does it get traced back to? Last owner of record, yes?
Even if a private transfer is technically legal, why would you want that liability hanging over your head?
Same reason I've never understood the upside of straw purchases for the official buyer of record. Sure, somebody pays you to make the official buy, but then you're on the hook for whatever happens with that gun.
