Very obviously individuals were expected to be part of the militia, which was the military at the time (c.f. the Militia Acts 2 years after ratification requiring individual gun ownership and very clearly laying out that all able-bodied white male citizens aged 18-45 were part of the militia), but also states could regulate weapons if they wanted.
Not a firearm.
I didn’t say we could ban compressed air powered guns, I specifically said percussion caps. The Girardoni was way less dangerous than a modern handgun.
In the 230 intervening years, we've vastly increased the scope of the federal government and developed a formal military, so one might argue we ought to amend the constitution to change exactly what's allowed under 2A (e.g. it should be straightforward to have a nuclear weapons ban added with unanimous agreement), but as it stands, 2A (+14A) clearly gives individuals the right to own the arms necessary to run a functioning ("well-regulated") militia, which in 2026 means at least semi-automatic firearms.
Thrown stones are a fast firing deadly weapon. They, compressed air guns, and ball musket etc aren’t used by modern military forces in combat because they are less dangerous.
A rule that allows compressed air weapons yet bans percussion caps is quite reasonable and could pass constitutional scrutiny.
Banding heavy machine guns yet another invention after the constitution was written didn’t, so there’s clear present this wouldn’t either.
Supreme court rulings are arbitrary as they regularly reverse or update standards, sometimes multiple times.
Saying what arguments are right doesn’t make sense in these contexts only what is the current precedent.
From Heller v. DC:
“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, and the Fourth Amendment applies to modern forms of search, e.g., Kyllo v. United States, 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.”
A few years after that ruling, the Massachusetts state supreme court upheld a conviction for a woman who had carried a taser for self defense. The Supreme Court accepted her challenge, allowed it to go forward without paying court costs, and unanimously overturned that ruling without asking for oral arguments ( https://supreme.justia.com/cases/federal/us/577/411/ ):
“The court offered three explanations to support its holding that the Second Amendment does not extend to stun guns. First, the court explained that stun guns are not protected because they ‘were not in common use at the time of the Second Amendment’s enactment.’ This is inconsistent with Heller’s clear statement that the Second Amendment ‘extends . . . to . . . arms . . . that were not in existence at the time of the founding.’
“The court next asked whether stun guns are ‘dangerous per se at common law and unusual,’ in an attempt to apply one ‘important limitation on the right to keep and carry arms.’ ... In so doing, the court concluded that stun guns are ‘unusual’ because they are ‘a thoroughly modern invention.’ By equating ‘unusual’ with ‘in common use at the time of the Second Amendment’s enactment,’ the court’s second explanation is the same as the first; it is inconsistent with Heller for the same reason.
“Finally, the court used ‘a contemporary lens’ and found ‘nothing in the record to suggest that [stun guns] are readily adaptable to use in the military.’ But Heller rejected the proposition ‘that only those weapons useful in warfare are protected.’
“For these three reasons, the explanation the Massachusetts court offered for upholding the law contradicts this Court’s precedent.”
The fact that Caetano was a unanimous and thorough ruling says a lot to me. Perhaps you’re holding out hope that Heller will be overturned soon, but the chances for that are very slim ( https://youtu.be/nFTRwD85AQ4 ).
Obviously there’s a bunch of exceptions, including as you point out the federal option of going through a background check and paying 200$/grenade. But that’s only at the federal level it doesn’t necessarily meet state requirements.
The rules on those background checks are as capricious as banning people who were dishonorably discharged from the military.
Sure but drivers licenses exist when no similar requirements existed for horse drawn buggies because the clear increase in relative danger to the public. When comparing newspapers with radio, the limited spectrum on radio was accepted as justification for more restricted speech etc.
Really citing when the court ruled one way vs another is less important than recognizing which kinds of arguments tend to resonate with the court as in the end specific cases are arbitrary decisions influenced by the specifics of the case.
“Repeating” here ignores the actual rate of fire of a Kalthoff or the even worse Cookson design. Especially when you consider how slow reloading is vs modern firearms.
How many lives would have been saved at the Las Vegas massacre if Paddock has been limited to these designs? I’d say 30 is a safe bet but that’s probably a low estimate.
State laws are another matter entirely, but even many states with stringent gun laws don't ban DDs specifically (probably because many lawmakers are not aware that such things are legal).
As for the background checks, I own over a dozen NFA-regulated items including a destructive device (a 40mm grenade launcher), and I can't say that the rules aren't really any more onerous than they are for regular firearms. This particular bit about "banning people who were dishonorably discharged from the military" applies equally to any firearm transfer under federal jurisdiction, for example (e.g. buying across state lines, or within states that mandate a federal check for anything). As I recall, the only thing that stood out in NFA forms compared to the regular stuff was the need to submit fingerprints. That aside, it was smooth sailing even back when I wasn't a citizen. So really the only barrier is affordability, and AFAIK this is exactly how the NFA was intended to work back when it was designed ($200 was about 4x the price of a full auto gun like Thompson back then, so it basically made them outlandishly expensive, only available to the rich).
