++++If you’ve ever purchased a gun and gone through the NICS background check you are in a federal database as a gun owner.+++++
^^^ THIS
Your name, DOB, drivers license and SS if entered was in their computer before you walked out the door with your purchase. Just the NICS clerk keying the query for the check into their system stores it in their system. Anyone that believes the feds ‘oh we dont save that data’ is prime target for selling unnamed bridges.
And if someone rented a gun at the range for the CCW qualifying test, then nobody knows for sure if they have a gun already.
And in some states CCW holders don’t need to go thru the NICS when they buy a gun from a FFL dealer, just the 4473 form gets filled out.
If it’s from a private party, then they get a bill of sale from the seller, and no form 4473.
