"Chicago - Gary. Gary - Chicago. Strict laws, to relaxed rules. Jump in a car, drive a short distance, buy a gun and head home."

Since you mention "strict laws" and "relaxed rules", I presume you're referring to lawful purchases. Based on the post to which you replied, I also presume we're talking about Chicago residents obtaining guns...

The conditions for a resident of IL **lawfully** buying a firearm in IN and bringing it back home to IL are:
* Firearm must be a rifle or shotgun
* Firearm must be purchased, in person, from an FFL (NOT a private party)
* Fill out form 4473 and submit to NICS check
* Transfer must fully comply with laws of both IL and IN
(all of the above is federal law - 18 USC 922)
* IL laws with which the transfer must comply:
- buyer must present IL FOID card to seller
- 24-hour waiting period for long guns

Of course, you don't have to jump through such hoops if you don't mind buying the gun **illegally**. But then, you wouldn't have to go to Gary to do that.
