Weapons Charges & Unlawful Use of a Weapon (UUW) in Illinois

Illinois has some of the strictest weapons laws in the country — and the penalties for violations are severe. Whether you're facing charges for carrying without a FOID card, possessing a firearm as a felon, or unlawful use of a weapon (UUW), the consequences can include years in prison. At Stavros Law Offices, we understand Illinois firearms law and aggressively defend weapons charges.

Common Weapons Offenses in Illinois

Unlawful Use of Weapons (720 ILCS 5/24-1)

UUW covers a broad range of weapons violations:

• Carrying a firearm without a valid FOID card
• Carrying a concealed firearm without a valid CCL
• Possessing certain prohibited weapons (machine guns, short-barreled rifles/shotguns, silencers)
• Possessing a firearm while under 21 (with exceptions)
• Carrying firearms on prohibited premises (schools, government buildings, etc.)
• Carrying brass knuckles, switchblades, or other prohibited weapons

Aggravated Unlawful Use of a Weapon (720 ILCS 5/24-1.6)

UUW becomes "aggravated" when:

• The firearm is loaded and immediately accessible
• The person is not on their own property or in their own vehicle
• Committed in a vehicle on a public way
• The person has a prior weapons conviction
• Committed while hooded or masked
• The person is a gang member

Unlawful Possession of Firearm (UUWF) / Felon in Possession

Under 720 ILCS 5/24-1.1, certain people are prohibited from possessing firearms:

• Convicted felons
• Persons convicted of domestic battery
• Persons convicted of certain misdemeanors (assault, battery, etc.) within 5 years
• Persons subject to an order of protection
• Persons adjudicated mentally disabled
• Persons under 21 (with limited exceptions)

Armed Habitual Criminal (720 ILCS 5/24-1.7)

Possessing a firearm after two or more qualifying felony convictions — extremely serious Class X felony.

FOID Card Requirements

Illinois requires a Firearm Owners Identification (FOID) card to possess firearms or ammunition. You must have a valid FOID to:

• Purchase firearms or ammunition
• Possess a firearm in your home
• Transport firearms (even unloaded)

FOID revocation can occur due to:

• Felony conviction
• Domestic violence conviction or order of protection
• Mental health adjudication or hospitalization
• Certain misdemeanor convictions
• Drug convictions

Concealed Carry License (CCL)

To carry a concealed firearm in public, you need a valid CCL in addition to your FOID. CCL holders must:

• Complete 16 hours of training
• Be at least 21 years old
• Not be prohibited from possessing firearms
• Comply with prohibited locations restrictions

Carrying without a valid CCL can result in felony charges.

Prohibited Locations

Even with a valid FOID and CCL, firearms are prohibited in:

• Schools and school property
• Government buildings
• Courts
• Airports and public transportation
• Bars (more than 50% alcohol sales)
• Public gatherings requiring permits
• Any property with posted "no firearms" signs

Defense Strategies

Illegal Search and Seizure

Many weapons charges stem from traffic stops, pat-downs, or vehicle searches. If police violated your Fourth Amendment rights, the weapon may be suppressed — often resulting in dismissal.

Lack of Knowledge

If you didn't know there was a firearm present (e.g., in a vehicle you borrowed), you may have a defense. Possession requires knowledge.

Constructive vs. Actual Possession

For "constructive possession" (firearm found near you but not on your person), the State must prove you knew about the weapon and had control over it.

Valid FOID/CCL

If you had a valid FOID or CCL at the time, charges may be challenged. Administrative errors sometimes result in wrongful charges.

Self-Defense / Necessity

In rare circumstances, possessing a weapon for immediate self-defense may provide a defense.

Challenging Prior Convictions

For "felon in possession" charges, we examine whether prior convictions were constitutionally valid and properly counted.

Firearm Sentencing Enhancements

Using a firearm during another offense triggers severe enhancements:

• 15 years added for possessing a firearm during certain felonies
• 20 years added for firing a weapon during a felony
• 25 years to life added for causing injury by firing during a felony

These enhancements are mandatory and consecutive — meaning they're served after the underlying sentence.

Probation Eligibility

Probation availability depends on the specific charge:

• Misdemeanor UUW: Probation and supervision available
• Class 4 Felony AUUW: Probation possible but prosecutor often objects
• Class 2/3 Felony: Probation possible for first offenders
• Class X Felony: Prison mandatory, no probation
• Armed Habitual Criminal: Prison mandatory

Frequently Asked Questions

Can I have a gun in my car?

With a valid FOID, you can transport an unloaded firearm in a case. With a valid CCL, you can carry a concealed, loaded firearm in your vehicle.

What if my FOID expired?

Possessing a firearm with an expired FOID is illegal. However, if you applied for renewal before expiration, you may have a grace period. We examine the specific facts.

Can I get my gun rights back after a felony?

Possibly. Illinois allows certain felons to apply for FOID restoration after a waiting period. The process involves a hearing before the Director of State Police.

Is a knife a weapon under Illinois law?

Certain knives are prohibited (switchblades, ballistic knives). Others are legal to possess but may be restricted for carry. A knife used as a weapon can result in aggravated assault or battery charges.
