Since I wasn't exactly clear on what the "LoopHole" on the "Closing the Gun-show Loophole" was I started researching what the real issue was. I found this bit of info while doing so. Granted it is from Wikipedia and no I don't believe everything posted on Wiki, it did come with a reference index, unfortunately when I went to that it required an account to log into. Anyway this is what is posted.
"A 1997 Department of Justice survey of 3,959 prison inmates found that only 2% stated that they had bought a gun used in a crime from a gun show.[10] The remaining 98% were obtained from other sources, in which the criminal had no direct connection with a gun show."
