Is it legal to buy some Glock magazines and barrel without a FOID in IL? Are the mags and the barrel considered accessories or they are in the same category as a handgun? My point is to have a LW conversion barrel and some mags ready to go, before I get the gun. With the lack of ammo these days, I wanna have all the options available. Some will say, get the gun first and then all the rest, but I don't wanna wait 2 weeks until I get ammo, or pay $30 a box at the range.
