They simply travel to the next state over, Indiana to purchase firearms and guns are brought into Chicago from Indiana and other states where gun laws are lax.
36K illegal guns taken off Chicago streets in recent years; trafficking remains a perplexing problem
https://wgntv.com/news/wgn-investig...rafficking-remains-a-perplexing-problem/This is why state laws and city laws alone will never address this problem.
Federal law allows you to travel to a different state to purchase a firearm, however, the purchase has to be legal in both states for you.
For instance, I cannot go to PA and purchase a Bushmaster AR-15 as it is banned, by name, here in MD. If a FFL sells it to me they are in violation and can lose their license. I can go purchase a Mossberg 500 though, as that is a legal, cash and carry item in both states. I cannot purchase a handgun out of state either since MD requires a permit to do so that I do not have.
