Massachusetts allows FTF between permit holders without a 4473 and without a NICS check, at least without a prerequisite NICS check. I've heard somewhere around here that they are supposed to conduct those checks after-the-fact when you transfer through the portal, though I really wouldn't know if they actually do or not. The major difference on the ground, so to speak, is that you can't escape the NICS check in the gun store by having a permit. Clearly the argument they are making in Georgia is that because you are a permit holder, you can fill out the 4473 and be done with it because you've already been checked. Not sure whether what the Dems propose for UBCs would exclude that or not. It's not really at issue.
The question was whether Pelosi2's (Clark's) numbers might be more or less correct. Pelosi2's numbers were 83% of gunowners and 74% of Republicans. A gunowner is anybody who owns a gun, including a great many people who have never bought one and including a sizeable percentage of Democrats, especially in the South. 74% of Republicans likewise would include people who have never even bought a gun and not a few that don't even own one. Almost certainly the numbers are different in Georgia because blue states are offsetting. I'm just not seeing any reason to doubt those numbers. The other point I was making is that I don't think UBCs will make a difference because I can't remember the last mass shooter who fits the bill of having purchased their firearms FTF without a NICS check. Almost always they obtained their guns from an FFL in a legal fashion. Sometimes they should have been denied but weren't. Sometimes they got their guns from the household. I think that terrorist couple from California did a straw purchase. Stuff like that I remember. I'm just not remembering any mass shooters who bought their AR from bubba down the street in a legal FTF transaction.
