California uses the technical feasibility of microstamping serial numbers onto a firing pin so as to require any new handguns added to the state’s “roster of safe handguns” have such a firing pin. The 25 micron relief of the stamping can be sanded off in like a minute so the tech is really just a de facto ban on any new designs being legally sold in the state
Oh I meant sanding the die off of the firing pin so it doesn’t stamp a serial number onto the casings; the projectile gets marked by the rifling upon firing. Wakmrow posted an article above about how the rifling analysis is subjective, unrepeatable pseudoscience but I don’t think it mentions that polygonal rifling is distinguishable from traditional land & groove rifling. So if a defendant is caught with, say, a glock, finding polygonal rifling on recovered bullets would make such analysis more damning in that case.
huh I thought guns had, like, microscopic “signatures” or serial numbers on the firing pin for some reason

Hmm, that’s only on the brass though, I guess marking the bullet would be significantly harder
