Reply #26: Correct, such a ban is unreasonable and contrary to the 2A and the Heller finding.

Some selected quotes from Heller that may apply to a magazine ban.



"The Second Amendment protects an individual right to possess a
firearm unconnected with service in a militia, and to use that arm for
traditionally lawful purposes, such as self-defense within the home."


holding that the sorts of weapons protected are those
“in common use at the time”


"The handgun ban and the trigger-lock requirement (as applied to
self-defense) violate the Second Amendment. The District’s total ban
on handgun possession in the home amounts to a prohibition on an
entire class of “arms” that Americans overwhelmingly choose for the
lawful purpose of self-defense. Under any of the standards of scrutiny
the Court has applied to enumerated constitutional rights, this prohibition—
in the place where the importance of the lawful defense
of self, family, and property is most acute—would fail constitutional
muster."

"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. It may well be true today that a militia, to be as
effective as militias in the 18th century, would require
sophisticated arms that are highly unusual in society at
large. Indeed, it may be true that no amount of small
arms could be useful against modern-day bombers and
tanks. But the fact that modern developments have limited
the degree of fit between the prefatory clause and the
protected right cannot change our interpretation of the
right."


"Some have made the argument, bordering on the frivolous,
that only those arms in existence in the 18th century
are protected by the Second Amendment. We do not interpret
constitutional rights that way. Just as the First
Amendment protects modern forms of communications,
e.g., Reno v. American Civil Liberties Union, 521 U. S. 844,
849 (1997), and the Fourth Amendment applies to modern
forms of search, e.g., Kyllo v. United States, 533 U. S. 27,
35–36 (2001), the Second Amendment extends, prima
facie, to all instruments that constitute bearable arms,
even those that were not in existence at the time of the
founding."


"We are aware of the problem of handgun violence in this
country, and we take seriously the concerns raised by the
many amici who believe that prohibition of handgun
ownership is a solution. The Constitution leaves the
District of Columbia a variety of tools for combating that
problem, including some measures regulating handguns,
see supra, at 54–55, and n. 26. But the enshrinement of
constitutional rights necessarily takes certain policy
choices off the table. These include the absolute prohibition
of handguns held and used for self-defense in the
home. Undoubtedly some think that the Second Amendment
is outmoded in a society where our standing army is
the pride of our Nation, where well-trained police forces
provide personal security, and where gun violence is a
serious problem. That is perhaps debatable, but what is
not debatable is that it is not the role of this Court to
pronounce the Second Amendment extinct."
