I'm from Illinois and I have found the regulations regarding muzzleloaders growing somewhat confusing for the past few years as well. Some suppliers will still ship them to Illinois residents without any restrictions, others do ask for a faxed copy of your FOID card. Before a few years ago, they would all ship them without a FOID card on file. I don't know what law, if any, was enacted to require them to ask for a FOID card. I would just fax a copy of your FOID card to them to "cover the bases" and order the Sidekick - which is a non-4473 gun anyway. Good thing we live in Illinois where we are so regulated and :roll: well protected from all the violence, crime, and mayhem caused by muzzleloaders!!!! I hope you get one and enjoy it. Good shootin'.
