- SV_BubbleTime 3y agoI just wrote about that. It absolutely is. The worst was when anti-gun groups were pushing “micro-stamping” of firing pins to imprint a number on the primer face. Complete and utter fantasy, easily defeat-able, unenforceable, nonsense. Didn’t stop them from pushing it for at least a decade. Even the bullet to barrel match of a gun fired in the lab is pretty much BS. You can tell major aspects like ”the gun this bullet came from had 5R or polygonal rifling” but that is about where it ends in reality. You can prove a bullet didn’t come from some gun, but pretty much never that it did.
- thereddaikon 3y agoIndeed. Not sure where the notion came from that devices mass produced with interchangeable parts would have some kind of mechanical fingerprint that could be forensically identified. Most modern handguns use the browning short recoil action. Of those, most use the Sig Sauer updated system. They are all going to do very similar things cases. That's by design. The most you may ever be able to prove is "yeah this was fired by a glock" Which is next to useless and even then I doubt it.
- SV_BubbleTime 3y agoThe factory Glock firing pin is a unique shape. You can tell on those. What you can’t tell is if someone swapped the firing pin for something rounder. Apparently the new small frame carry Glocks have round pins (42, 43, 48) https://hipowersandhandguns.com/Corbon%209mm%20115_files/image020.jpg https://hipowersandhandguns.com/Corbon%209mm%20115_files/ima...
