Regarding Illinois, it doesn't fall under the restrictions of a long gun or a shotgun, and (here' the rub) if it was designed to be held and fired with one hand, then it's an eligible weapon for Illinois Concealed Carry statute.

and Illinois doesn't require complete concealed.

“Concealed firearm” means a loaded or unloaded handgun
carried on or about a person completely or mostly concealed
from view of the public or on or about a person within a
vehicle.”
