The high-capacity magazine of the semiautomatic pistol used in the shooting of Rep. Gabrielle Giffords and more than a dozen other people on Saturday would have been illegal to manufacture and difficult to purchase under the Clinton-era assault weapons ban, which expired in 2004.
According to police and media reports, the alleged shooter, Jared Lee Loughner, legally purchased a semiautomatic Glock 19 with a high-capacity magazine in November at a gun store in Tucson. Under the assault weapons ban, it was illegal to manufacture or sell new high-capacity magazines, defined as those that hold more than 10 rounds. The magazines used by Loughner had 31 rounds each, according to police.
Ed. Note: I’ve edited the title of this entry to more accurately reflect the fact that the magazine used in the shooting was banned under the Clinton-era gun control laws, not the weapon itself.
