The "gun show loop hole" refers to the ability for non licensed (private) gun sales that do not require a back ground check.
Currently 20% of gun sales are private and do not require that check.
Keep up
There is a reason only 13 states have universal backgroud checks. It essentially creates a gun registry. It is bad enough that FFL dealers must keep their 4473's for 20 years and turn them over to ATF if they go out of business, which is very likely within a 20 year time span.
I am ok with universal background checks if we remove the 4473 requirement. A check is done at the time of purchase to make sure you should be able to purchase a gun. If you pass, the gun is sold and that is it. End of story. No records kept that shows x person purchased x gun.
The saving grace now is that most FFL dealers are ardent 2nd Ammendment supporters and aren't real keen in turning over their 4473's to ATF. In my state, if you have a concealed weapons permit,a 4473 is still filled out, but no call is made to ATF.
