Magazine Limits

High-capacity magazines allow firearms to be discharged rapidly and repeatedly without reloading, increasing the potential for them to harm more people in a short period of time. We support legislation prohibiting the sale and transfer of high-capacity magazines.

What are High-Capacity Magazines?

High-capacity magazines, also known as large-capacity magazines, are those that contain more than 10 rounds of ammunition. They can be used with any semi-automatic firearm that accepts a detachable magazine, including handguns, and allow the firearm user to fire repeatedly for longer periods of time without having to reload. 

Why Limit Capacity?

Every time a shooter must pause to reload, there is an opportunity for lives to be saved. High-capacity magazines drastically reduce the number of these opportunities, increasing the ability of a shooter to harm large numbers of people quickly. The shooter at Sandy Hook Elementary School had ten 30-round magazines in his possession. In 4 minutes, he shot 154 bullets, killing 20 children and 6 adults. When he had to pause to reload, 11 children were able to escape. 

How Effective Are Limits?

Laws restricting possession of high-capacity magazines have been shown to be the best predictors of a state’s rate of mass shootings.1 States without laws limiting magazines have significantly more high-fatality mass shootings and significantly higher death rates from such incidents than states with limits in place.2

From 1994 to 2004, federal law made it illegal to transfer or possess large capacity magazines in the US. During this time, mass shooting fatalities were 70% less likely to occur than in periods before or after the law’s enforcement.3 After the law expired in 2004, there was a 183% increase in in high-fatality mass shootings and a 239% increase in deaths resulting from such shootings.4

Which States Have Magazine Limits?

As of June 2020, nine states and the District of Columbia have laws in place restricting the sale and possession high-capacity magazines: California, Colorado, Connecticut, Hawaii, Maryland, Massachusetts, New Jersey, New York, and Vermont.

How can we pass magazine limits?

The Keep Americans Safe Act (H.R. 1186/ S. 447) would prohibit the transfer, import and possession of magazines able to hold more than 10 rounds of ammunition. It was introduced in the Senate by Senator Bob Menendez (D-NJ) and in the House by Representatives Ted Deutch (FL-22), Diana DeGette (CO-01) and Dina Titus (NV-01).
