In the 18 incidents that included Large Capacity Magazines (LCMs), 371 were killed and 715 were wounded, with hundreds more suffering non-gunshot injuries. Almost all of these massacres occurred in minutes, with shooters firing dozens and, often times, hundreds of bullets. 12 incidents included militiary-style assault weapons.
More People are Killed When LCMs are Used
This data is backed up by a 2019 study entitled “The Effect of Large Capacity Magazine Bans on High-Fatality Mass Shootings, 1990-2017,” published in the American Journal of Public Health. Their analysis provides answers to important questions:
- How often are LCMs used in high-fatality mass shootings? LCMs were used in 64% of high-fatality mass shootings between 1990 and 2017.
- Are more people killed when LCMs are used? Yes – 11.8% were killed when LCMs were used vs. 7.3% when LCMs were not used.
- Do states with LCM bans experience fewer mass shootings and lower fatalities than states with no bans? Yes.
