What It Does

Fully automatic machine guns—those that fire bullets in rapid succession with a single pull of the trigger—and the parts used to create them have been tightly regulated under federal law since the 1930s.1US Bureau of Alcohol, Tobacco, Firearms and Explosives, “National Firearms Act,” April 7, 2020, https://www.atf.gov/rules-and-regulations/national-firearms-act. However, the gun industry and third-party sellers continue to produce devices that make it easy to convert semi-automatic firearms into illegal machine guns in a matter of minutes. Auto sears, often in the form of “Glock switches,” alter the trigger mechanisms of semi-automatic pistols and rifles, enabling the guns to continuously fire rounds as long as the trigger is depressed and the gun has ammunition. These devices can allow pistols to fire at rates of up to 1,200 rounds per minute.2U.S. Attorney’s Office for the Northern District of Texas, “Fort Worth Manufacturer Charged in Glock Switch Case,” press release, November 18, 2022, https://www.atf.gov/news/press-releases/fort-worth-manufacturer-charged-glock-switch-case. Auto sears are small in size and simple in design which makes them easy to manufacture, or simply 3D print.3Alain Stephens and Keegan Hamilton, “The Return of the Machine Gun,” The Trace, March 24, 2022, https://www.thetrace.org/2022/03/auto-sear-gun-chip-glock-switch-automatic-conversion/.

The Impact

Between 2017 and 2021, the ATF recovered 5,454 machine gun conversion devices, including Glock switches, a 570% increase from the preceding five years.1US Bureau of Alcohol, Tobacco, Firearms and Explosives, “National Firearms Commerce and Trafficking Assessment (NFCTA): Crime Guns – Volume Two: PART VII: Recommendations and Future Enhancements,” January 2023, https://www.atf.gov/firearms/docs/report/nfcta-volume-ii-part-vii-recommendations/download. Tragically, these devices have been recovered at numerous crime scenes across the country.2US Bureau of Alcohol, Tobacco, Firearms and Explosives, “National Firearms Commerce and Trafficking Assessment (NFCTA): Crime Guns – Volume Two: PART VII: Recommendations and Future Enhancements,” January 2023, https://www.atf.gov/firearms/docs/report/nfcta-volume-ii-part-vii-recommendations/download.
