On June 26, 2008, the U.S. Supreme Court struck down the ban on small arms and light weapons in Washington, D.C. in the District of Columbia v. Heller. [121] Chicago and other municipalities have come under legal pressure to change their laws. [122] [123] In the months following the Heller decision, small arms bans in the suburbs of Wilmette,[124] Morton Grove,[125] Evanston,[126] and Winnetka,[127] were lifted, but Chicago and Oak Park retained their laws. [126] [128] To legally possess firearms or ammunition, Illinois residents must have a Firearms Owner Identification Card (FOID) issued by the Illinois State Police based on the issuance of targets. Non-residents who are legally authorized to possess firearms in their home state are exempt from this requirement. Possession of firearms, variously defined as assault weapons, is also illegal in Lincolnwood, Skokie, Evanston, Highland Park, North Chicago, Melrose Park, Riverdale, Dolton, Hazel Crest, Homewood and the Buffalo Grove portion of Cook County. The storage or transportation of assault weapons is restricted in Morton Grove, Winnetka, Country Club Hills and University Park.

[93] [94] [95] [96] [97] [98] [99] The sale and transfer of offensive weapons is prohibited in Niles.[100][101][102] and commercial sales are prohibited in Naperville. [103] In December 2015, the U.S. Supreme Court dismissed Friedman v. Highland Park, a challenge to the city`s ban on offensive weapons. [104] Deerfield adopted regulations in 2013 regulating the storage and transportation of assault weapons and high-capacity magazines; In April 2018, the regulation was amended to prohibit possession. [105] [106] In June 2018, the enactment of the law was blocked by a Lake County Circuit Court judge who found that the order violated a state pre-emption law. In March 2019, the judge ruled that the law was invalid and permanently prohibited the village from enforcing it. [107] [108] [109] In December 2020, a state appeals court overturned the judgment and allowed the ban to take effect. [110] In November 2021, the Illinois Supreme Court upheld this decision by a 3-3 vote. [111] Illinois treats certain powder-free weapons as firearms, defines high-performance and/or large-caliber unpudished weapons as firearms, and therefore makes all purchase, possession, and transfer requirements under state law applicable to such weapons. Illinois excludes from the definition of firearms any air pistol, suspension barrel, colored bullet gun, or B-B pistol that does not exceed a single bullet projectile, 18 inches in diameter or with a maximum muzzle velocity of less than 700 feet per second, or that emits bullets of fragile color with washable marking colors.1 The open carrying of firearms is generally illegal, except when hunting or on one`s own land or in one`s own country or in one`s own country or in one`s own country. Housing or permanent establishment or in the country or in the apartment or permanent establishment of another person with the permission of that person.

[41] [42] Single or double barrel muzzle loading rifles of .45 caliber firing a single projectile through a barrel at least sixteen inches in length. A muzzle-loading weapon is defined as a firearm that cannot be loaded from the end of the shutter. Only black powder or a black powder substitute such as Pyrodex can be used. Modern smokeless powders are a black powder substitute approved only in mouth-loading guns specially designed for their use. Percussion caps (shotgun primers are legal), wheel locks, matches, or flint ignition can only be used for Connecticut Valley Arms electronic ignition, which is legally authorized to use. In Illinois, it is illegal to unload air guns from or through a road, sidewalk, road, highway or public land, or public place, except in a safely constructed target area.6 It is also illegal for a person under the age of 13 to carry an air rifle on public roads or property unless the person wears the Unloaded air rifle.7 A person under the age of 13 may possess an air rifle, if this is the case: Cook County has prohibited the possession of certain semi-automatic firearms that it has defined as offensive weapons. [83] [84] Residents must report to the district sheriff within 48 hours any firearms stolen, lost, destroyed, sold or otherwise transferred. The sheriff may share this information with other law enforcement agencies. [85] [86] Licensed arms dealers must provide the county with information about buyers and the weapons they purchase, and obtain a licence before making sales. [87] A person may not purchase more than one firearm within 30 days. [88] In a home where a person under the age of 21 is staying, all weapons must be secured with a trigger lock or kept unloaded in a locked container separate from the ammunition or attached to the body of the rightful owner. [89] In Cook County, local laws, such as those in Chicago, take precedence over county laws that govern similar matters.

[90] Cook County levies a twenty-five dollar tax on the sale of firearms by a retail dealer, in addition to the county`s usual sales tax. The county also has a tax on the sale of ammunition — five cents per shot for center-fire ammunition and one cent per shot for rim-firing ammunition. [91] [92] Chicago has banned the possession of certain semi-automatic firearms, which it defines as offensive weapons, as well as laser sights. [74] [75] Chicago residents must “immediately” report a stolen or lost firearm and report the transfer of a firearm within 48 hours of such transmission. [76] In a home where a person under the age of 18 is staying, all weapons must be secured with a trigger lock or stored in a locked container or attached to the body of the rightful owner. [77] Some local governments have knife laws that are more restrictive than those of the state. In Chicago, it is illegal to carry a knife with a blade larger than 64 mm (2.5 inches) in length. [138] To obtain a FOID card, a person must generally be over the age of 21 or have the written consent of their parents or guardians to possess and purchase firearms and ammunition.5 (In the latter case, the person`s parents or guardians should not be prohibited from obtaining a FOID card themselves).6 Even with parental consent, people under the age of 21 are not entitled to a FOID card, if they have been convicted of a misdemeanor (other than a traffic offense) or convicted of other offenses as offenders.7 In Illinois, muzzle magazines and black powder guns are considered firearms. [18] To purchase or possess a Taser or stun gun, a Firearms Owner Identification Card (FOID) is required.
