Understanding what guns are legal in Illinois in 2025 requires navigating a complex framework of state statutes and local ordinances, building upon a foundation of federal law. While the Second Amendment protects the right to keep and bear arms, Illinois imposes specific regulations that dictate which firearms are permitted, who can possess them, and how they can be carried. This landscape is defined by the Illinois Firearm Concealed Carry Act and the broader Illinois Compiled Statutes, with ongoing discussions about potential legislative changes shaping the current environment. Prospective gun owners must look beyond the basic federal definitions to understand the nuanced rules specific to the state.
Overview of Illinois Gun Laws
Illinois operates under a "shall-issue" policy for concealed carry permits, meaning authorities must grant a license to qualified applicants who meet specific criteria. The primary legislation, the Firearm Concealed Carry Act, established a framework for lawful concealed carry after a Supreme Court ruling mandated it. However, this permission to carry does not equate to a free-for-all; the law meticulously defines prohibited persons and outlines strict requirements for eligibility. Compliance hinges on understanding these statutes, which govern not just carrying, but the very legality of owning specific types of firearms within state borders.
Permitted Firearm Categories
Generally, standard handguns, rifles, and shotguns are legal for ownership and possession in Illinois, provided they meet certain criteria. Unloaded long guns can typically be transported in a vehicle, provided they are in a case, locked in the trunk, or otherwise inaccessible to the driver. For handguns, the focus shifts to the licensing process for carrying them concealed. While open carry is largely restricted in public places, the possession of long guns within a private residence or on private property is generally lawful. Key examples of legal handguns include popular models from manufacturers like Glock, Sig Sauer, and Springfield Armory that comply with state safety standards.
Semi-automatic pistols with a fixed magazine capacity.
Lever-action and bolt-action rifles.
Standard capacity shotguns for home defense and sport shooting.
Long guns transported securely in a vehicle for lawful purposes like hunting or target practice.
Assault Weapons and High-Capacity Magazines
One of the most significant aspects of what is legal in Illinois involves the state's ban on assault weapons and high-capacity magazines. Illinois has specific statutes that prohibit the manufacture, sale, and possession of assault weapons and magazines that hold more than 10 rounds. This ban, however, includes provisions for registration for weapons acquired before the ban took effect, allowing existing owners to retain them under strict conditions. Understanding the precise definition of an "assault weapon" as outlined in the law is critical, as it determines the legality of many modern sporting rifles and pistols. Possession of a non-compliant magazine, even in a legal firearm, is a distinct violation of state law.
Key Restrictions and Prohibited Persons
Even if a firearm model is generally legal, a person may be prohibited from owning or carrying it. Illinois law defines "prohibited persons" comprehensively, including individuals convicted of certain felonies, those subject to restraining orders for domestic violence, and individuals adjudicated as mentally defective or committed to a mental institution. Furthermore, it is unlawful for any person to knowingly sell or transfer a firearm to someone they know is prohibited. Background checks are mandatory for all firearm sales through licensed dealers, and private sales are also regulated to ensure transfers do not circumvent these safety checks. Drug users and those who have renounced U.S. citizenship also fall into the prohibited category.
Felons convicted of a crime punishable by imprisonment for one year or more.
Individuals under a restraining order for domestic violence.
Those with a documented mental illness that poses a danger to themselves or others.
Unlawful users of or addicted to any controlled substance.
