What is the Process to Legally Purchase a Firearm in Cook County?

To purchase a firearm in Cook County, an individual must be at least 18 years old for long guns (rifles and shotguns) and 21 years old for handguns (pistols and revolvers). They must also be a resident of the county and possess a valid Firearm Owner’s Identification (FOID) card, which is issued by the Illinois State Police. To obtain a FOID card, an individual must submit an application, which requires them to provide personal information, including their name, date of birth, and residential address, as well as a valid government-issued identification.

In addition to the FOID card requirement, there are also several other laws and regulations that must be followed when purchasing a firearm in Cook County. For example, all firearm purchases must be completed through a licensed firearms dealer, and the dealer must conduct a background check on the purchaser using the National Instant Criminal Background Check System (NICS). This background check is used to ensure that the purchaser is not prohibited from owning a firearm due to prior criminal convictions, mental illness, or other disqualifying factors.

There are also several laws that regulate the sale of firearms in Cook County. For example, it is illegal for anyone to sell a firearm to a minor or to someone who is not a resident of the county. It is also illegal to sell a firearm to someone who is prohibited from owning one due to prior criminal convictions or mental illness. Additionally, it is illegal to sell a firearm without conducting a background check through a licensed firearms dealer.

In addition to the laws and regulations mentioned above, there are also several other restrictions and requirements that must be followed when buying or selling a firearm in Cook County. For example, it is illegal to possess certain types of firearms, such as machine guns, short-barreled rifles, and sawed-off shotguns.
