"With its large ammunition capacity, quick reloading, light trigger pull, and utter reliability, the Glock was hugely innovative — and an instant hit with police and civilians alike. Headquartered in Deutsch-Wagram, Austria, the company says it now commands 65 per cent of the American law enforcement market. The Toronto and Durham police forces are also all-Glock, with Toronto’s emergency task force equipped with the same gun Loughner is alleged to have used. With all those customers and that visibility, it’s no surprise that the Glock has also been the gun of choice for some prolific psychopaths. Byran Uyesugi used a Glock 17 to kill seven people at a Xerox office in Honolulu in 1999. Seung-Hui Cho, who murdered 32 at Virginia Tech in 2007 before killing himself, used the same Glock 19 model that Loughner is accused of firing in Tucson. Steven Kazmierczak packed a Glock 17 when he shot 21 people, killing five, at Northern Illinois University in 2008. The smooth-firing Glock did not cause these massacres any more than it holds up convenience stores. But when outfitted with an extra-large magazine, it can raise the body count. The shooters in Arizona, Illinois, Virginia, Hawaii, and Texas could not have inflicted so many casualties so quickly had they been armed with old-fashioned revolvers. In its 2010 catalog, the manufacturer boasts that while the Glock 19 is “comparable in size and weight to the small .38 revolvers it has replaced,” the pistol “is significantly more powerful with greater firepower and is much easier to shoot fast and true.” The Tucson gunman demonstrated those qualities all too vividly. Loughner is said to have emptied his 33-round clip in a minute or two, a feat requiring no special skill."
