There is no federal registry, that's why the FFL system exists. They track who they did transactions with and if the federal government needs to know about a transaction they can approach the FFL holders. The system works as designed to preserve privacy while also providing some amount of traceability. All that needs to happen is the prohibition of private sale outside of an FFL. From there you can penalize gun shows that allow non-FFL holders to sell. As I said earlier, there's not a good reason not to transact through an FFL. They're charged with maintaining your privacy as a purchaser while simultaneously preventing strawman purchases. They're a very basic extension of nearly every pawn broker.
