A Federal requirement that whenever ownership of a handgun is transfered, a licensed firearms dealer does a background check and registers the firearm to it's new owner. Private sales would have to be finalized at a dealers shop. If this is not done, the prior owner remains responsible for whatever is done with the firearm.
It's already the law in California, for all firearms other than curio and relics, other than the bolded section above.
Hasn't had any noticable effect on criminal misuse of firearms, but it gives the state DOJ bureau of firearms a reason to exist, and costs firearms owners $25.00 per DROS (Dealers Record of Sale)
On the federal level you'd have a problem with the FOPA (firearms Owners Protection Act) wrt your registration scheme - no federal gun registration of title 1 firearms is permitted under that law:

The Act also forbade the U.S. Government agency from keeping a registry directly linking non-National Firearms Act firearms to their owners, the specific language of this law ( Federal Law 18 U.S.C. 926 (2) (a)) being:
No such rule or regulation prescribed after the date of the enactment of the Firearms Owners Protection Act may require that records required to be maintained under this chapter or any portion of the contents of such records, be recorded at or transferred to a facility owned, managed, or controlled by the United States or any State or any political subdivision thereof, nor that any system of registration of firearms, firearms owners, or firearms transactions or disposition be established. Nothing in this section expands or restricts the Secretary's authority to inquire into the disposition of any firearm in the course of a criminal investigation.
