What It Does
These laws prohibit the purchase of high-capacity magazines, which are ammunition-feeding devices designed for lethality—enabling a shooter to fire more rounds without pausing to reload. States have typically defined high-capacity to include magazines that hold more than 10 rounds, though a few states provide different thresholds. A full discussion on High-Capacity Magazines is here and here.
The Impact
Since 2016, all 10 of the highest casualty mass shootings have involved the use of at least one firearm equipped with a high-capacity magazine.1The 10 highest casualty mass shootings from 2016 to 2025 occurred in: Las Vegas, NV (2017); Orlando, FL (2016); Highland Park, IL (2022); Sutherland Springs, TX (2017); El Paso, TX (2019); Uvalde, TX (2022); Parkland, FL (2018); Midland-Odessa, TX (2019); Lewiston, ME (2023); and Dadeville, AL (2023). Everytown for Gun Safety Support Fund, “Guns Used in the Deadliest U.S. Mass Shootings,” The Smoking Gun, accessed January 7, 2026, https://smokinggun.org/guns-used-in-the-deadliest-u-s-mass-shooting/. Research shows that states with restrictions on magazine size experience mass shootings at less than half the rate of states without restrictions.2Louis Klarevas, Andrew Conner, and David Hemenway, “The Effect of Large-Capacity Magazine Bans on High-Fatality Mass Shootings, 1990–2017,” American Journal of Public Health 109, no. 12 (2019): 1754-61, https://doi.org/10.2105/AJPH.2019.305311. Study defined mass shooting as six or more shot and killed, excluding the shooter; Sam Petulla, “Here Is 1 Correlation between State Gun Laws and Mass Shootings,” CNN, October 5, 2017, https://cnn.it/2J4sWCC. Study defines mass shootings as incidents where three or more victims, not including the shooter, are shot and killed or shot and wounded.
