text: Justice Antonin Scalia's opinion for the majority provided Second Amendment protection for commonly used and popular handguns but not for atypical arms or arms used for unlawful purposes, such as short-barreled shotguns. Scalia stated: "Whatever the reason, handguns are the most popular weapon chosen by Americans for self-defense in the home, and a complete prohibition of their use is invalid." "We think that Miller's "ordinary military equipment" language must be read in tandem with what comes after: "[O]rdinarily when called for [militia] service [able-bodied] men were expected to appear bearing arms supplied by themselves and of the kind in common use at the time." 307 U. S., at 179." "We therefore read Miller to say only that the Second Amendment does not protect those weapons not typically possessed by law-abiding citizens for lawful purposes, such as short-barreled shotguns." "It may be objected that if weapons that are most useful in military service – M-16 rifles and the like – may be banned, then the Second Amendment right is completely detached from the prefatory clause. But as we have said, the conception of the militia at the time of the Second Amendment's ratification was the body of all citizens capable of military service, who would bring the sorts of lawful weapons that they possessed at home to militia duty."
