The District’s handgun ban is a reasonable and constitutional restriction because handguns are less effective than other firearms for self-defense. Although they are designed to be more lethal than other firearms, handguns are smaller and harder to shoot accurately.

The amount of twisting the anti-gun lobby has to apply is staggering. To them, a handgun, which applies exponentially less power than a rifle, is designed to be more lethal but is smaller and less effective. In the real world, that would render it "less lethal". And unless I'm mistaken, the 2nd Amendment does not read
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms of a specific design of lethality, shall not be infringed.
