In response to the devastating mass shooting in Tucson earlier this month, which left six dead and thirteen wounded, Congresswoman Carolyn McCarthy has introduced H.R. 308, which would ban large capacity ammunition magazines. Large capacity ammunition magazines are frequently used in mass shootings, including the tragedy in Tucson and those at Columbine High School, Virginia Tech, Fort Hood, and 101 California Street in San Francisco, because they enable a shooter to kill large numbers of people in a matter of seconds.

The Law Center needs your help to tell Washington how vital this legislation is to the prevention of future mass shootings. Here’s what you can do:

Sign our petition urging Congress to pass H.R. 308, Congresswoman McCarthy’s bill to ban large capacity ammunition magazines. Forward this e-mail to your friends and urge them to sign the petition as well!

Contact your U.S. Representative at (202) 224-3121 and encourage him or her to cosponsor H.R. 308. If you’re not sure who your Representative is, you can find that information at

Call President Obama at (202) 456-1111 and urge him to announce his support for H.R. 308.

Large capacity ammunition magazines have no place in civilian hands. As discussed in our updated policy summary, large capacity magazines were banned under a now-expired federal law, and are now only prohibited in California and five other states. Act now to stop the sale of these magazines and help prevent future tragedies!
