Section 24-3 of the Illinois Criminal Code (720 ILCS 5/24-3) criminalizes the unlawful sale, delivery, or transfer of firearms to prohibited persons and in prohibited circumstances. The statute addresses both individual transactions and high-volume illegal gun trafficking, with a penalty structure that escalates dramatically based on the number of firearms involved.[1]
Prohibited Transfers
Section 24-3(a) makes it unlawful to knowingly sell, manufacture, purchase, possess, or carry certain weapons or to deliver them to persons under specified circumstances. The most commonly charged provisions involve:[1]
- Selling or giving any firearm to a person under 18 years of age (with limited exceptions for supervised sporting activities and parental transfers)
- Selling or giving any firearm to a narcotic addict
- Selling or giving any firearm to a person who does not hold a valid FOID card
- Selling or giving any firearm to a person who is a convicted felon or is otherwise prohibited from possessing firearms under state or federal law
- Delivering a firearm of a size which may be concealed upon the person, incidental to a sale, without withholding delivery for at least 72 hours after the application for purchase (the mandatory waiting period)
Straw Purchases
Section 24-3 also addresses straw purchases -- transactions in which one person purchases a firearm on behalf of another who is prohibited from making the purchase themselves. A person who knowingly acquires a firearm for someone who is prohibited from possessing it commits a violation of this section. Straw purchases are a significant enforcement concern in Illinois, as they are a primary channel through which prohibited persons obtain firearms.[1]
Graduated Penalty Structure -- Trafficking Provisions
The most distinctive feature of Section 24-3 is its dramatically escalating penalty structure for high-volume unlawful firearm sales. Penalties are classified as Class X felonies and scale based on the number of firearms involved and the timeframe of the illegal activity:[1]
- 6 to 10 firearms (sold at the same time or within a 2-year period): Class X felony, 6 to 30 years in prison
- 11 to 20 firearms (within a 3-year period): Class X felony, 6 to 40 years in prison
- 21 to 30 firearms (within a 4-year period): Class X felony, 6 to 50 years in prison
- 31 or more firearms (within a 5-year period): Class X felony, 6 to 60 years in prison
These sentencing ranges are among the most severe in the Illinois Criminal Code for non-homicide offenses. The escalating structure reflects the General Assembly's view that large-scale illegal gun trafficking is a primary driver of firearms violence and warrants penalties comparable to major narcotics trafficking.[1]
Base-Level Penalties
For unlawful sales that do not meet the volume thresholds above, penalties vary by the specific violation:
- Selling or giving a firearm to a person under 18: Class 4 felony (1 to 3 years) as the baseline under 720 ILCS 5/24-3(g); enhanced to a Class 3 felony for handgun transfers or repeat violations, and to a Class 1 felony (4 to 15 years) when the sale occurs within 1,000 feet of a school
- Selling a firearm to a person without a valid FOID card: Class 4 felony (1 to 3 years)
Interaction with Dealer Licensing
Section 24-3 operates alongside the Firearm Dealer License Certification Act (430 ILCS 68), which requires all Federal Firearms Licensees in Illinois to obtain an additional state-level certification. Dealers who violate transfer requirements may face charges under both statutes, as well as revocation of their state and federal dealer licenses.[2]
Universal Background Check Requirement
Since July 1, 2023, the Protect Illinois Communities Act requires all private (non-dealer) firearm transfers to go through either a licensed dealer who conducts a background check or through the ISP's online FOID verification system. Private sellers who fail to verify the buyer's FOID card or conduct the required background check may face charges under Section 24-3 in addition to penalties under the Protect Illinois Communities Act itself.[3]
