Illinois firearms laws govern how residents and visitors may purchase, possess, carry, and use firearms within the state. This guide covers the most important aspects of Illinois gun laws as of 2026, including purchase requirements, carry permits, waiting periods, and self-defense statutes. Always consult official state statutes and legal counsel for binding legal guidance.
Permit to purchase: FOID card required for all purchases. Illinois requires a permit, license, or ID card before you can purchase certain firearms. This additional step involves a background check and may add processing time to your purchase. Buyers must be at least 21 years old for handguns and 18 years old for long guns (rifles and shotguns). All purchases through licensed FFL dealers require a federal NICS background check.
Background checks: State background check via FOID system. When you purchase a firearm on WeaponDepot, it ships to your chosen FFL dealer in Illinois who handles all required paperwork and background check processing.
Waiting period: 72 hours for handguns, 24 hours for long guns.
Open carry: Prohibited.
Concealed carry: CCL required from Illinois State Police. Illinois operates under a permit-based carry system. Residents must apply for and obtain a concealed carry permit before legally carrying a concealed firearm in Illinois. Check local requirements for application procedures, fees, and training requirements.
Assault weapons ban (2023), FOID requirement, universal background checks. Federal restrictions on NFA items (short-barreled rifles, suppressors, machine guns) still apply and require ATF approval through the appropriate tax stamp process.
Illinois follows the duty-to-retreat doctrine, which generally requires individuals to retreat if safely possible before using deadly force in public. The state also provides limited Castle Doctrine provisions.
Illinois has enacted a red flag law (Extreme Risk Protection Order). This law allows law enforcement or family members to petition a court to temporarily remove firearms from individuals deemed a danger to themselves or others. Additionally, Illinois has state preemption, meaning local municipalities cannot enact firearms laws stricter than state law.
When you purchase a firearm on WeaponDepot, it ships directly to a licensed FFL dealer in Illinois. At the dealer, you complete ATF Form 4473 and undergo the required background check. FFL transfer fees in Illinois typically range from $15 to $75 per firearm. Use our FFL dealer directory for Illinois to compare fees and find the best dealer near you.
