Banning detachable magazines is all the rage among the
anti-gun crowd. However, several recent Supreme Court cases clearly
demonstrate that such a law would violate the Second Amendment. The
Court has repeated ruled that weapons “in common use at the time” are
protected for use by the Second Amendment. Firearms with detachable
magazines have been “in common use” for over a century.
As noted in
part one of this series, California’s state legislature
passed a bill that
would have banned firearms that accept detachable magazines. The bill
failed to become law only because
California Governor Brown vetoed it.
Gun control advocates have recently put forth the idea of banning
detachable magazines as a means of crime reduction or reducing mass
murders. MIT Economics Professor
Chris Knittel’s made this suggestion in an OpEd earlier this year. The idea has also been put forth by other
anti-gun fanatics and
unscrupulous politicians.
In part one, we covered why the banning detachable magazines would not
have any measurable impact on crime, homicides, or decrease in mass
murders. Here in part two, we will cover why a ban on detachable
magazines would be unconstitutional in violating the Second Amendment.
In several recent (and one not-so-recent) cases, the Supreme Court
has ruled that the Second Amendment: protects the individual’s right to
keep and bear arms (
D.C. v Heller, 2008); that arms lawfully protected are those “in common use at the time” (
U.S. v Miller, 1939;
Heller, 2008;
McDonald v Chicago, 2010); and the 14th Amendment extends Second Amendment protections to all states (
McDonald,
2010). In the light of these Supreme Court rulings, it is clear any
state or federal law banning detachable magazines would violate the
Second Amendment’s protections to the people’s civil right to keep and
bear arms.
In
Heller, The Supreme Court defined what “arms” means in legal and historical context:
Before addressing the verbs “keep” and
“bear,” we interpret their object: “Arms.” The 18th-century meaning is
no different from the meaning today…defined “arms” as “weapons of
offen[s]e, or armor of defen[s]e.”…Timothy Cunningham’s important 1771
legal dictionary defined “arms” as “any thing that a man wears for his
defence, or takes into his hands, or useth in wrath to cast at or strike
another” (p.7).

All firearms constitute arms according the Supreme Court: “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” (p.8). While this doesn’t mean any arms whatsoever, in
Heller the Court upheld previous legal restrictions from
Miller
on “dangerous and unusual” weapons. It should be noted that “dangerous
and unusual” weapons are specifically defined and highly regulated under
the 1934 National Firearms Act (NFA). They are also not “banned”, but
are legal to own, provided the proper paperwork is filed with the ATF.
“Dangerous and unusual” does
not mean semi-automatic rifles and handguns, which are not regulated by the NFA.
The Court stated that what is protected are arms “in common use at the time” in
Miller,
Heller and
McDonald. Rifles with magazines have been in existence for nearly two centuries. A
magazine is an ammunition storage and feeding device
in a firearm, and may be internal or detachable. All rifles, with the
sole exception of single-shot rifles, have them. Rifles with magazines
have been common since the 1800′s; the first bolt-action rifle
was invented in 1824. Bolt-action and lever-action rifles with magazines became increasingly prevalent throughout the 1800′s: the
Spencer repeating rifle utilized a tube magazine, while the
M1885 Remington-Lee which featured an internal box magazine.
Colt .45 handgun, featuring detachable magazines. Invented in 1911, still “in common use” today.
Detachable magazines have existed since the early 1900′s. The
1911 Colt .45 handgun, still “in common use” today, features detachable magazines. The
Thompson “Tommy Gun”
rifle, invented in 1919, also features detachable magazines. The
Remington Model 8 and 81, first developed in 1906 with attached box
magazines, was
adapted in the 1920′s for detachable box magazines.
Today, detachable magazines are common in everything from bolt-action
rifles, like the Remington 700 to semi-automatic rifles like the AR-15,
Mini-14, M-14, FAL, G3/H&K 91 type, AK47 variants and many others,
and virtually all semi-automatic handguns. Because today’s detachable
magazines are so common, many people think of magazines as separate
objects, but they are integral to the function of rifles.

1906; detachable magazines were available by the 1920s.
The Court has also said in
Heller it is unconstitutional to
ban an entire class of weapons popularly chosen by the American people
(p.56-57). The Court also said that constitutionally protected rights
are not subject to an interest-balancing approach, meaning the right
can’t be limited just because gun violence is a problem (p.62-63). The
Court states, “we are aware of the problem of [gun] 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…But the
enshrinement of constitutional rights necessarily takes certain policy
choices off the table” (p.64). Similarly, semi-automatic rifles and
handguns that utilize detachable magazines have been overwhelmingly
chosen by the American people for lawful purposes including home and
self-defense and hunting. The Court stated in
Heller “as we have explained [from
Miller],
that the sorts of weapons protected were those “in common use at the
time” (p.55). A law banning them would violate the Second Amendment.
