I'm a gun owner, but I find the popularity among civilians of weapons intended for military or police use to be very disturbing. Civilians do not need handguns with 20 round capacities. Such weapons are not meant for defense against home invaders. They're meant for combat and police situations where avoiding the need to stop and reload can be the difference between life and death. In civilian hands, they do nothing but multiply the damage when some idiot goes on a rampage. If the guy in Arizona had used a 5-shot revolver he'd never have gotten off 31 shots. And any homeowner who thinks he needs anything more than that 5-shot revolver to protect his home needs to spend more time at the firing range learning to aim, not more money for a higher capacity gun so he can spray bullets indiscriminately.
