When guns are outlawed, only...yawl know the rest. Apparently this law only applies to semi-automatic handguns. Revolvers are not yet required to have the stamping capability. But we know if this law passes and is upheld in the courts, all the rest of the firearms will have to follow suit. Article doesn’t say if currently owned firearms are grandfathered in does it?
I wish Mr Chiaramonte knew a little bit about his subject before writing an article like this. He states: “The telltale mark theoretically allows law enforcement investigators to trace the bullet to the registered gun owner.” Law enforcement is not going to track down any perpetrators if they find a “bullet” because the the marking is put on the shell casing by the firing pin.
It would be minimally useful because revolvers do not eject spent brass, and there would be nothing left for investigators to investigate.
