Section 7-2507.02 ... amounts to a complete prohibition on the lawful use of handguns for self-defense. As such, we hold it unconstitutional.

To summarize, we conclude that the Second Amendment protects an
individual right to keep and bear arms. That right existed prior
to the formation of the new government under the Constitution and
was premised on the private use of arms for activities such as hunting
and self-defense, the latter being understood as resistance to either
private lawlessness or the depredations of a tyrannical government
(or a threat from abroad). In addition, the right to keep and bear arms
had the important and salutary civic purpose of helping to preserve the
citizen militia. The civic purpose was also a political expedient for
the Federalists in the First Congress as it served, in part, to placate
their Antifederalist opponents. The individual right facilitated militia
service by ensuring that citizens would not be barred from keeping the arms
they would need when called forth for militia duty. Despite the importance
of the Second Amendment's civic purpose, however, the activities it protects
are not limited to militia service, nor is an individual's enjoyment of the
right contingent upon his or her continued or intermittent enrollment in the
militia.
