What Illinois Considers a Weapon Offense

Illinois law covers a wide range of firearm and other weapon conduct under the Criminal Code’s Deadly Weapons article. Common charges include:

• Unlawful Use of Weapons (UUW) and Aggravated Unlawful Use of a Weapon (AUUW) for carrying on or about the person or in a vehicle in prohibited ways or without required authorization. See 720 ILCS 5/24-1 and 720 ILCS 5/24-1.6.
• Unlawful possession of firearms or ammunition without a valid FOID card. See 430 ILCS 65/2.
• FOID or Concealed Carry License (CCL) violations, such as expired or revoked credentials, or carrying in prohibited areas. See the Firearm Concealed Carry Act (430 ILCS 66).
• Defacing or possessing a defaced firearm. See 720 ILCS 5/24-5.
• Possession of a firearm by a felon. See 720 ILCS 5/24-1.1.
• Prohibited weapons or devices (for example, certain explosive devices) and, under more recent law, assault weapon and large-capacity magazine restrictions. See 720 ILCS 5/Art. 24, 720 ILCS 5/24-1.9, and 720 ILCS 5/24-1.10.

What the State Must Prove

Prosecutors must prove each element beyond a reasonable doubt. In firearm cases, elements often include:

• Knowing possession or control of the item.
• That the item meets Illinois definitions for a firearm or prohibited weapon.
• Location and manner of carry (on person, in a vehicle, loaded/accessible) that satisfy the statute.
• Lack of required authorization when the statute makes authorization an element (for example, no valid FOID or CCL).

Some offenses add aggravators such as prior convictions, protected locations (like schools or public transit), or specific intent.

FOID and Concealed Carry Basics

In Illinois, you generally need a valid FOID card to possess firearms or ammunition. See 430 ILCS 65/2. To carry a concealed handgun in public, a Concealed Carry License is required. See the Firearm Concealed Carry Act (430 ILCS 66). CCL holders must present their license to an officer upon request during a lawful encounter. See 430 ILCS 66/10.

There are specific transport rules for firearms in vehicles, and certain places are off-limits even for licensees (for example, schools, courthouses, and public transportation facilities). See 430 ILCS 66/65. Statutes and court decisions evolve, so always verify current rules.

Powerful Defense Strategies

• Illegal stop, search, or seizure: Move to suppress the firearm or statements if police lacked reasonable suspicion, probable cause, a valid warrant, or if the search exceeded its lawful scope. See 725 ILCS 5/114-12.
• Lack of knowing possession: Challenge control or knowledge, especially in shared spaces, multi-occupant vehicles, or borrowed property.
• Not a firearm or not operable as charged: Dispute classification, operability, or alleged modifications.
• FOID/CCL compliance or statutory exceptions: Show valid licensing, timely renewals, or transport exceptions where applicable.
• Unreliable evidence: Attack chain of custody, body-cam gaps, lab results, or witness credibility.
• Constitutional issues: Assert Second Amendment or state constitutional arguments where supported by current case law.

Penalties and Collateral Consequences

Illinois weapons offenses range from misdemeanors to serious felonies. Exposure can turn on prior convictions, location (e.g., protected areas), whether a firearm was loaded/accessible, and any related conduct. Collateral consequences can include immigration risks for non-citizens, loss of firearm rights, employment and professional licensing issues, and impacts on housing or education. Outcomes can be shaped by mitigation, treatment programs, and negotiation.

What To Do If You’re Stopped With a Firearm

• Stay calm and keep your hands visible.
• Provide identification as required by law.
• Exercise your right to remain silent and ask for a lawyer.
• Do not consent to a search.
• If you have a FOID or CCL, follow disclosure obligations carefully (CCL holders must disclose and present the license upon request to an officer). See 430 ILCS 66/10.

FAQ

Yes. In Illinois, possessing ammunition generally requires a valid FOID card. See 430 ILCS 65/2.

Can a CCL holder carry everywhere?

No. Certain locations remain off-limits even for licensees, including schools and courthouses. See 430 ILCS 66/65.

What if the police stopped me without reasonable suspicion?

Your lawyer may file a motion to suppress unlawfully obtained evidence. If granted, the case can be dismissed or reduced. See 725 ILCS 5/114-12.

Are there defenses if the gun was in a shared car or home?
