That may be true, but why is the type of gun and the serial number part of the background check? How does that help keep criminals and the mentally ill from getting guns? We are not stupid. We know what you really want.
Let's hypothesize for a moment. Let's pretend I'm either a criminal or somebody who has been in and out of mental hospitals with a history of serious mental illness. I know either of these will show up on a background check, and I know individuals meeting these conditions aren't supposed to own guns. So, I willingly go to a legal gun dealer, hand over all my personal information, and subject myself to a background check, knowing it will disqualify me from getting the gun I want to purchase???? Does that make ANY sense? Of course not. If I meet either of these conditions, I stay far away from legal gun sales and buy my gun off the streets. And if I'm mentally ill, but haven't been flagged by the system yet, a background check won't stop me from purchasing, so I fall through that crack. Do these idiots even listen to the words that are coming out of their mouths, or are they just on auto-pilot?
