California May Require Pistol ID's
Hoping to find shooting suspects more quickly, California may become the first state to require semiautomatic poistols to stamp their make, model and serial number onto every cartridge they fire. Proposed legislation would require semiautomatic models produced after January 2007 to carry the microstamping techniology by which serial numbers are laser-etched onto a guns firing pin, which then transmits them to the bullet casing when the trigger is pulled. Critics claim the bill would raise the price of handguns without having much practical effect, because criminals would simply buy old guns, replace the firing pins or alter firing pins to erase indentifying markers.
