Not betting my pinky finger on this but I'm pretty sure the only record of a dealer gun sale in virgina is the hardcopy of a bill of sale and pertainent details kept on site at the dealers business and the -I think it's called a NICS application. Nation instant crime sume sumpin - FBI Database. Anyway state police nor local townships are involved in any way when a gun is purchased. Federally licensed dealers are required to keep all these record imperptuity. And all local gun laws and registration schemes were preempted by state law consolidating the power of the state to regulate guns. You see with the a web of different local laws people will unwittly break the law by driving across some abitrary county or city line. Many states are instituting preemption laws - thank god!
Actually - I think the Va. state police run the NICS checks so they are involved, however I don't think they keep any documents as the gun dealer calls in the check and gives I believe your name address and SS#. It's a quick call accept waiting on hold for 30 minutes or so until they get thumbs up or thumbs down.
