So exactly why do you need a modern pistol with a capacity for over 7 bullets?

Nobody outside of police or military could conceivably need such a thing. But, to the NRA and their gun-nut followers, it's not about need. It's about want. They want them in the same manner that a four-year-old wants the latest toy advertised on television, for pretty much the same reasons, and they pitch pretty much the same sorts of tantrums when someone tries to tell them they can't have it.

What I don't get is this: Federal migratory waterfowl laws limit the capacity of repeating shotguns in the field to three rounds. Most pump-action or automatic shotguns have an actual capacity of five shells, but removable plugs are inserted to reduce that capacity to three for duck hunting. Nobody complains about it. It's like someone has decided ducks have more right to a reasonable chance of survival than humans. If you want to hunt mallards, you only get three shots before you have to reload, but if you want to hunt movie-goers, kindergartners, or Democratic politicians you can use as big a magazine as you can get your hands on.
