Pennsylvania is a POC (Point of Contact) State which means the State does the background checks instead of using the Fed NICS. Having the state doing the background checks opens up 'possibilities' that the state will also collect 'additional' information than what the Feds do. As that thread says, Washington State does this as well and they are too a 'POC state.
Kentucky uses Federal NICS for both handguns and long guns. Therefore there is no information going to Frankfort on what you bought at the LGS (Local Gun Store) because they call the Fed NICS not the State POC NICS...there is no State POC here in KY.
Some people think having the state doing the NICS instead of the Fed NICS is a good idea...well it isn't.
(Supposedly the state DOES run checks WITH the FED NICS on their CDWL holders. One source said it was monthly, another source said periodically. But the back ground checks they do has nothing on what you bought. But rather just to see if CDWL holders still have clean back ground checks)
