"Shot for shot, either a .45-caliber Colt 1911 or a .44 Smith & Wesson revolver will do more damage than a Glock nine-millimeter. Still, a Glock, or another large-capacity semiautomatic, can make a very bad situation even worse. During a mass shooting, such as the Luby’s massacre in 1991, a deft gunman can fire more rounds and reload more quickly with a modern pistol equipped with hefty magazines. When Seung-Hui Cho slaughtered thirty-two classmates and professors at Virginia Tech in April 2007, he used two pistols: a nine-millimeter Glock 19 and a smaller .22-caliber Walther. Considerable media attention focused on the fifteen-round compact Glock and the fact that it enabled Cho to unleash a greater volume of rounds in less time. Whether his choice of the Austrian brand raised the horrific body count remains a matter of speculation. It probably did. There is no question that Jared Lee Loughner created more carnage in January 2011 because he brought a newly purchased Glock 19 to a political gathering in a shopping mall in suburban Tucson, Arizona. On a sunny Saturday morning, Loughner, a deranged twenty-two-year-old, opened fire at a constituent meet-and-greet hosted in front of a Safeway supermarket by his congresswoman, Gabrielle Giffords. In just minutes, the gunman sprayed thirty-three rounds, killing six people and wounding thirteen others, including Giffords, who suffered severe brain damage from a point-blank shot that passed through her head. Among the dead were a federal judge and a nine-year-old girl who served on her elementary school student council and wanted to shake hands with the vivacious politician. Loughner used a special oversized magazine, making it possible for him to do much more damage in a matter of minutes than he otherwise might have. He did not stop firing until he had to pause to reload and attendees at the event tackled him. Since the expiration in 2004 of the ten-round ammunition cap, Glock has led the charge back into the large-capacity magazine business. Sportsman’s Warehouse, the Tucson store where Loughner bought his Glock, advertises on its website that “compact and subcompact Glock pistol model magazines can be loaded with a convincing number of rounds—i.e.… up to 33 rounds.” The scale of the bloodshed in Tucson, like that at Virginia Tech and Luby’s, presents the strongest possible evidence that a restriction on magazine size makes sense. Such a limit would not stop a Loughner or Cho from attacking, but it could reduce the number of victims. Only six states—California, Hawaii, Maryland, Massachusetts, New Jersey, and New York—have their own limits on large magazines. A national ten-round cap seems like a logical compromise that lawful gun owners could easily tolerate. The NRA has concluded otherwise—and pushed the issue off the legislative table."
