In SC and I think in N.C. too, when you fill out a 4473 form, a copy DOES NOT go to any government agency. It stays in the possession of the FFL holder with the exception that if you purchase multiple handguns in a 7 day period, those purchases are reported. So unless the government knows which dealer to call, they have no clueIf you ever bought a brand new gun, it is easily traced to you with 1 or 2 phone calls from the .gov.
