Furthermore rimfire cartridges are particularly difficult to microstamp due to the nature of how rimfire bullets work. Getting consistent prints, even with a fully functional gun, is very difficult.
Fair, Trunk, but the radial marks are on the sides of the pin, and like a pencil when you use it, there is still a few cm's behind it with the same mark on it.
If because of this people just end up nabbing their spent shells, you've only made the job of tracking them down more difficult. seems to me like a net loss.
I don't know whether to laugh at how dumb this is or cry because people who have the power to actually make this happen think this way.
Well, maybe not NJ, their gun regulations are a nightmare. Let's say PA then.
It refers to a general design of pocket pistol and is a bastardization of the name of the maker of one of the original designs, "Deringer".
Also Ybbat, what's to stop Remington from just simply moving their business out of state and into a state without this law?
Suddenly it's a useless law on the books as no manufacturers will be making these stamps.
Read up on the CSSA and NFA, they have a lot more to say on how piss-poor our gun laws are than I do.
Queue ignorant firearm arguments!
Gun control in this country is unconstitutional and is designed specifically to make shooting too boring and too much of a hassle, so then less people will do it making it easier to pass gun control because less people care. There is nothing "fair" about the Firearms Act, it's an attocious piece of legislative garbage that has failed to prevent a single robbery, murder, or suicide, which means it has failed its intended purposes wholly and utterly. Read up more about it, you'll find out just how atrocious it is, how it allows a man who fired at idiots firebombing his house to face the possibility of more jail time than the culprits, all because the police ALLEDGE he had a pistol in his nightstand, yet they can't prove it. That's the Firearms Act, a pile of shit that tries to send a man who was defending himself to jail for trying to do it with a gun.
I kinda like the idea of tagging spent cartridges with information from the gun that fired them, but this is far from foolproof. Any jerkoff can make one quick swipe over the pin with a file and erase the markings, and normal wear will get rid of them quickly as well.
Besides, if your firing pin breaks or goes bad or gets lost, what are you gonna do? Send off your information and wait for some company to microstamp you a new one?
Also anything like this will be obsolete when people can simply 3d print their gun parts with plans on TPB.
From a physics perspective, yes, anything etched into a firing pin(especially the tip) will quickly be worn off by the firing of the weapon, irregardless of what the pin is made of.
This is one of those things that sounds like a decent idea until you think about it for like five seconds.
There are so many ways around it it's just ridiculous and I think the general consensus is that most criminals avoid legal methods of weapon acquisition anyways.
I wanna have your baby dacommie
Impractical. It would make manufacturing more expensive. Firing pins could get damaged by the gun functions. So many unmarked firing pins available. Anyone with a bit of gun smith, craftsmanship, or machining knowledge could make their own "off the grid" firing pin.
Just seems like a detrimental move to the gun industry, gun enthusiasts, and our freedom in general.
Let's assume we're using a 9mm Glock with a titanium firing pin and firing generic Federal ammo. The activation energy for titanium to undergo plastic deformation (read: to smoosh and make the numbers illegible) is 192.8 Kilojoules/mole. A mole of titanium is 47.9 grams of the stuff, a bit more than our firing pin's head, and much more than the stamp, which is going to be about 1.9 milimeters wide with, going by the UC Davis study, 0.143 mm depressions, so about half of a 40.5 mm^3 cylinder of "stuff" we could deform if we wanted to smear the whole head. Titanium has a density of 4.51 grams per cm^3, and our half cylinder of stuff is 0.02025 cm^3, so we have 91.3 milligrams of titanium on the head. We get moles again from dividing mass by molar mass, so 0.0913/47.9 or 0.00191 moles of titanium, leaving us with an activation energy of 368.2 joules necessary to deform the firing pin's head.
There's somewhere between 441 to 537 joules coming out of the barrel of this Glock, and since Newton's third law hasn't been repealed, we know that's about what's acting on the firing pin initially while the projectile gets the fuck out. However, the firing pin isn't just sitting there the entire time, it scoots backwards immediately after that brief impulse. Plastic deformation takes time. The resistance behind the firing pin is obviously pretty fucking low, obviously, since otherwise the gun wouldn't be semiautomatic. The much bigger issue is depositing of funny junk along the firing pin during that initial moment where the cartridge jams it backwards, but without extensive testing off sweaty brass-on-titanium action I can't comment on that.
This would be in keeping with the UC Davis study, where the primary issues were on tiny little guns that didn't have enough room for the striker to move and ended up grinding the firing pin port itself or large guns that obviously just chewed up the stamp. So it'd totally work for large semiautomatic pistols. Or, at least, a Glock, for a while. And then for anything with a delay before the firing pin is completely free (rifles) or has too little room to move (small guns) it's a terrible idea unless you start tipping pins with unique diamonds.
The real issue is, this adds $50 to the cost of a factory Glock just in materials, and etching titanium ain't like dusting crops. The industry dudes saying it's a $200 per gun thing are pretty accurate considering the engineering nightmare this is.
I think the bigger issue here is the fact that law enforcement knows murderers favor revolvers in fairly large calibers, which microstamping does jack shit to. Also, stolen guns, considering you can ruin the stamp with a rock. This is going to affect violent criminals who behave unlike the majority of violent criminals.
