Weapons Offenses Defense

Facing Gun Charges?

Illinois has some of the most complicated weapons laws in the country — a FOID card, a separate concealed carry license, and a patchwork of statutes that can turn a legally owned firearm into a felony charge based on where it was, how it was loaded, or whether paperwork was on hand at the moment of a stop. W. Scott Hanken has spent 37+ years in Illinois courtrooms, including time as a Sangamon County prosecutor, and knows exactly how these cases are built — and where they tend to fall apart.

A Former Prosecutor on Your Side

Most weapons charges in Illinois don’t start with someone trying to commit a violent crime — they start with a traffic stop, a misplaced FOID card, or a firearm stored the wrong way in a vehicle. The gap between “legal gun owner” and “felony defendant” in Illinois is often just a technicality, which is exactly why the details of how police discovered the weapon matter so much.

Attorney Hanken brings the perspective of having prosecuted these cases before spending decades defending against them. He’s rated Avvo 10.0 “Superb,” has been voted “Best Attorney” by both the Illinois Times and the State Journal-Register, and has earned 270+ five-star Google reviews and 340+ five-star FindLaw reviews. His office is in Springfield, a short walk from the Sangamon County Courthouse where most local weapons cases are heard.

Weapons Charges We Defend

This office handles the full range of Illinois firearm and weapons charges, from licensing violations to the most serious felony gun offenses.

Commonly defended charges include:

• Unlawful possession of weapons (formerly unlawful use of a weapon, or UUW)
• Aggravated unlawful possession of a weapon (formerly aggravated unlawful use of a weapon, or AUUW)
• Unlawful possession of weapons by felons
• Unlawful possession of a firearm by a repeat felony offender (formerly armed habitual criminal)
• FOID card and concealed carry license (CCL) violations
• Possessing a firearm during the commission of another offense
• Discharging a firearm during the commission of another offense
• Possessing a stolen weapon
• Illegal possession of a suppressor, knife, stun gun, or other prohibited weapon

Illinois renamed several of these offenses effective January 1, 2025. Older police reports and court records may still use the former names.

FOID Cards & Concealed Carry: The Legal Foundation

Nearly every Illinois weapons charge traces back to one of two documents — a Firearm Owner’s Identification (FOID) card and, for carrying concealed, a Concealed Carry License (CCL) — and not having either at the wrong moment is often the entire basis for a felony charge.

Illinois requires a FOID card simply to possess a firearm or ammunition, separate from any license needed to carry it. Carrying a concealed firearm additionally requires a CCL, which involves 16 hours of firearms training, written and range qualification tests, fingerprints and a photo, and a $150 fee for a five-year license. Carrying a loaded, uncased, immediately accessible handgun without a CCL is a Class 4 felony in Illinois, even for someone who legally owns the firearm and holds a valid FOID card. Even licensed CCL holders remain barred from carrying in certain locations — schools, government buildings, courthouses, public transportation, hospitals, stadiums, establishments that earn more than half their receipts from alcohol, and any private property posted with the official no-firearms sign.

Unlawful Possession of Weapons (Formerly UUW): The Base Offense

Fix A: restore the rest of the bold summary. The full sentence should read:

Unlawful possession of weapons — formerly called unlawful use of weapons — under 720 ILCS 5/24-1 is Illinois’s broadest weapons statute — it covers everything from carrying a concealed handgun without a license to possessing a switchblade, and most violations start as a Class A misdemeanor before anything else elevates them.

Common violations include:

• Carrying a pistol, revolver, or other firearm in a vehicle or concealed on your person without a valid CCL, unless it is unloaded and enclosed in a case (with a valid FOID card), broken down, or not immediately accessible
• Carrying a stun gun or taser in a vehicle or concealed on your person unless it is broken down, not immediately accessible, or enclosed in a case by someone with a valid FOID card — a concealed carry license does not cover stun guns or tasers
• Possessing a switchblade knife, dagger, dirk, stiletto, or other “dangerous knife” with a blade over three inches
• Possessing brass or metal knuckles, a blackjack, or a slingshot-style weapon
• Possessing a machine gun, silencer, or short-barreled rifle or shotgun

A firearm that’s unloaded, cased, and possessed by someone with a valid FOID card — or a handgun carried in compliance with a valid CCL — generally falls outside this statute entirely. The switchblade restriction specifically doesn’t apply to a valid FOID cardholder. Most violations are Class A misdemeanors, but some — like possessing a machine gun — escalate to a Class 2 or even Class X felony depending on the circumstances.

Aggravated Unlawful Possession of a Weapon (Formerly AUUW): When the Base Offense Becomes a Felony

The same basic conduct — carrying a firearm outside your home or fixed place of business — becomes a felony under 720 ILCS 5/24-1.6 the moment one specific aggravating factor is added, and the most common one is a loaded handgun carried by someone who was never issued a concealed carry license.

Aggravating factors that elevate the base offense to a felony include:

• A handgun was uncased, loaded, and immediately accessible, and the person had never been issued a concealed carry license
• A handgun was uncased and unloaded with ammunition immediately accessible, and the person had never been issued a concealed carry license
• A rifle, shotgun, or other non-handgun firearm was uncased, loaded, and immediately accessible, or uncased and unloaded with ammunition immediately accessible — a concealed carry license is no defense
• The person had never been issued a currently valid FOID card
• The person was under 21 and possessed a handgun (outside lawful Wildlife Code activities and a few other exceptions)
• The person had an order of protection issued against them within the previous 2 years
• The person was committing a misdemeanor involving the use or threat of violence, or a misdemeanor drug offense
• The person had been adjudicated delinquent as a juvenile for a felony-level offense

A first offense is a Class 4 felony — 1 to 3 years in the Illinois Department of Corrections and a fine up to $25,000. Probation may be available, except where the statute requires prison: a first offense combining a loaded, uncased, accessible firearm with no FOID card calls for 1 to 3 years in prison. A second or subsequent offense, or one committed by someone with a prior felony, is a Class 2 felony carrying 3 to 7 years. The offense escalates to a Class X felony when committed while wearing or possessing body armor without a valid FOID card.

One important protection: a concealed carry licensee who simply forgets the license at home generally faces only a Class B misdemeanor under the Concealed Carry Act — not a felony — as long as the license is valid and the licensee is otherwise eligible.

This is exactly why a routine traffic stop — with a legally owned handgun loaded and within reach of a driver who never got a concealed carry license — can turn into one of the most serious weapons charges on the books.

Felon Firearm Rights: Possession by a Felon & Repeat Felony Offenders

For anyone with a prior felony conviction, possessing a firearm — or even ammunition — is itself a felony in Illinois, even inside your own home, and the penalties escalate sharply with the prior record.

• Unlawful possession of weapons by felons (720 ILCS 5/24-1.1) is a Class 3 felony with a statutory range of 2 to 10 years. It becomes a Class 2 felony (3 to 14 years) for a second violation, for someone on parole or mandatory supervised release, or when the prior conviction was a forcible felony, a felony weapons offense, stalking, or a Class 2 or greater drug felony.
• Unlawful possession of a firearm by a repeat felony offender (720 ILCS 5/24-1.7, formerly called armed habitual criminal) applies to anyone found in possession of a firearm after two or more qualifying prior convictions. It’s a Class X felony — one of the most serious classifications in Illinois, carrying a mandatory 6 to 30 years in prison and fines up to $25,000.

These cases frequently turn on whether the firearm was actually in the person’s possession — actual or constructive — and whether the search that discovered it was lawful in the first place.

Restoring firearm rights after a felony is possible, but it means clearing two separate bans. Illinois relief comes through the FOID Card Review Board or, for certain serious offenses, the circuit court under 430 ILCS 65/10. In 2026, the U.S. Department of Justice reopened federal restoration under 18 U.S.C. § 925(c) through its Federal Firearm Rights Restoration program.

Carrying a Firearm in Your Vehicle: Illinois’s Safe Transport Rules

Illinois law treats a firearm in a vehicle differently depending on whether it’s loaded, cased, and accessible — and getting this wrong is one of the most common ways a legal gun owner ends up facing a felony charge.

Without a CCL, a loaded handgun within reach — on the seat, under it, or in an open compartment — can support a felony charge of aggravated unlawful possession of a weapon. The Illinois Supreme Court has held that a closed center console can count as a “case,” but the transport exception also requires the gun to be unloaded. Rifles and shotguns must follow the same unloaded-and-cased rule even for concealed carry license holders. Even a legally owned firearm can become the basis for a felony charge if it isn’t stored correctly during transport. For the full rules, see Can You Carry a Gun in Your Car in Illinois?

Suppressors, Knives, Stun Guns & Brass Knuckles: Illinois’s Other Weapons Restrictions

Beyond firearms, Illinois restricts or outright bans a range of other weapons — and some of these rules surprise even careful gun owners.

• Suppressors (silencers): Illinois bans civilian possession of suppressors — there is no exception for hunting, for sport shooting, or based on federal ATF registration. Possessing a suppressor is a Class 3 felony in Illinois, regardless of whether it’s legally registered federally.
• Knives: Switchblades and knives with blades over three inches used or carried as weapons fall under the same UUW framework as firearms. The switchblade restriction doesn’t apply to valid FOID cardholders or licensed knife dealers.
• Stun guns and tasers: Stun guns and tasers: You need a valid FOID card to possess one. A concealed carry license does not cover stun guns or tasers, so carrying one concealed or in a vehicle is generally lawful only if it is broken down, not immediately accessible, or enclosed in a case.
• Brass knuckles: Possession of metal or brass knuckles is prohibited outright under the same statute that governs blackjacks and other concealed weapons — and for someone with a prior felony, even simple possession of brass knuckles can support a felon-in-possession charge.

How We Fight Weapons Charges

Many weapons cases are won or lost on the same question: was the search that found the weapon actually lawful, and can the State prove you knowingly possessed it?

Common defense strategies include:

• Challenging the search — vehicle and person searches during traffic stops are one of the most frequent sources of weapons charges, and an unlawful search can result in the evidence being suppressed entirely
• Disputing possession — particularly in shared vehicles or residences, proving you knew about and controlled the weapon is the State’s burden, not a given
• Documentation defenses — Documentation defenses — the felony factors turn on whether a FOID card or CCL was ever issued, not whether it was in your pocket, so a valid card or license that simply wasn’t on hand at the time of the stop can often reduce what looked like a felony charge to a misdemeanor or less
• Challenging prior-conviction predicates — in felon-in-possession and armed habitual criminal cases, whether a prior conviction actually qualifies as a predicate offense is often contestable
• Negotiating reductions — Negotiating reductions — from felony aggravated unlawful possession of a weapon (AUUW) down to misdemeanor unlawful possession of weapons (UUW), or from a felony to a diversion program, particularly for first-time offenders
