On Tuesday, the City of Chicago announced a first-of-its-kind lawsuit against Glock, the manufacturer of the most popular handguns in the United States, alleging that Glock is facilitating the proliferation of illegal machine guns on the streets of Chicago. The lawsuit alleges that Glock unreasonably endangers Chicagoans by manufacturing and selling in the Chicago civilian market semiautomatic pistols that can easily be converted to illegal machine guns with an auto sear – a cheap, small device commonly known as a “Glock switch.” The suit is the first to use Illinois’s new Firearms Industry Responsibility Act, passed and signed into law in 2023 to hold gun companies accountable for conduct that endangers the public. 

Filed earlier Tuesday in Cook County Circuit Court, the lawsuit reports that law enforcement personnel in Chicago have recovered over 1,100 Glocks that have been converted into illegal machine guns in the last two years alone in connection with a wide variety of crimes, including homicides, aggravated assaults, batteries, kidnappings, burglaries, home invasions, carjackings, and attempted robberies. The lawsuit alleges that Glock knows it could fix the problem but refuses to do so, and the City is seeking a court order requiring Glock to cease sales of its easily converted pistols to Chicago civilians. The City also seeks penalties against Glock and damages for the harm that Glock has caused to the City.  The lawsuit is filed by the City of Chicago Law Department along with Everytown Law and Paul, Weiss, Rifkind, Wharton & Garrison, LLP.
