As a whole, until the waiting period is eliminated in IL, gun shows, that have guns for sale, are pretty much not going to fly.
If someone could go to a gun show, buy a firearm, from a ffl, or someone w/o a license, who wants to get rid of something they no longer want, and have a background check done, and go home
with the gun, like most other states, I think we'd see a lot more.
Right now, it is just a hassle, to buy a gun at a gun show, and then have to travel to the dealer's premises, to pick it up.
In some states, dealers travel 100 miles or more to these shows, because they can sell and have the new firearm owner take possession immediately.
That's just not practical for buyers or sellers in this state, with the onerous waiting period.
In some areas, around Chicago, politics, figure into whether certain venues are available to gun show promoters.
