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 a firearm that may be concealed upon the person to a person under 18 (720 ILCS 5/24-3(A)(a)), or selling or giving any firearm to a person under 18 who does not hold a valid FOID card (24-3(A)(i)), 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 any firearm, incidental to a sale, without withholding delivery for at least 72 hours after application for purchase (720 ILCS 5/24-3(A)(g), the mandatory waiting period, which applies to every firearm type)
Straw Purchases
Straw purchases, transactions in which one person purchases a firearm on behalf of another who is prohibited from making the purchase themselves, are addressed by a separate statute, 720 ILCS 5/24-3.5 (unlawful purchase of a firearm). A person who knowingly acquires a firearm for someone who is prohibited from possessing it violates that 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 the escalating penalty structure in 24-3(C)(10), which applies only to delivery of firearms the offender knew to be stolen or converted under 24-3(A)(l). These penalties are Class X felonies and scale with the number of stolen firearms involved and the timeframe:[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 concealable firearm to a person under 18: Class 2 felony (720 ILCS 5/24-3(A)(a), (C)(3)). Selling or giving any firearm to a person under 18 who lacks a valid FOID card: Class 3 felony (24-3(A)(i)). A waiting-period violation under 24-3(A)(g) is a Class 4 felony (24-3(C)(1))
- 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 FOID Act as amended by Public Act 102-237 (430 ILCS 65/3(a-10)) requires private (non-dealer) sellers either to verify the buyer's FOID card through the ISP's online system or to process the transfer through a licensed dealer. Failing to run the verification check is expressly not a criminal offense under 24-3(C)(7), but transferring a firearm to a person who does not hold a valid FOID card remains a felony, and record-keeping violations are penalized under the FOID Act (430 ILCS 65/14).[3]
