Witness Reports of Rapid-Fire Shooting Show Urgent Need to Crack Down on Growing Public Safety Threat of DIY Machine Guns Made With a “Switch”
For Immediate Release
June 23, 2026
CHICAGO – The Gun Violence Prevention PAC of Illinois (G-PAC), the state’s leading gun violence prevention organization, today issued a statement following the weekend’s mass shooting in Chicago’s Roseland neighborhood, where witnesses reported rapid fire shooting that injured as many as 14 people.
“The mass shooting in Roseland is a devastating reminder that our communities are being terrorized by DIY machine guns,” said Kathleen Sances, G-PAC President and CEO. “Standard handguns are being transformed into weapons of war in seconds, and the General Assembly must stop these deadly conversion devices from devastating neighborhoods and lives.”
DIY machine guns are made using a “switch,” which is no bigger than the size of a coin and turns a standard, semi-automatic pistol into an automatic weapon. Switches are banned both federally and in Illinois, but their availability is growing because they are inexpensive devices that can be easily obtained, including by using a 3D printer.
According to Everytown for Gun Safety, Chicago police recovered more than 1,600 switches between 2021 and 2024, including at two mass shootings, and they are believed to have been used in shooting deaths of several law enforcement officers.
The Responsible Gun Manufacturing Act (House Bill 4471/Senate Bill 2801), sponsored by Rep. Justin Slaughter and Sen. Celina Villanueva, will go further than current laws by banning the sale of weapons in Illinois that can be converted into illegal machine guns. It would require the industry to put in place safer design to prevent guns from being converted and prevent DIY machine guns from being made in the first place.
