A hotly contested California gun-control law that was passed in 2007 is finally ready to be implemented, state Attorney General Kamala Harris said last week. The requirement that every new semiautomatic handgun contain "micro-stamping" technology would allow police to trace a weapon from cartridges found at a crime scene.

Gun owners group Calguns Foundation tried to forestall the law at one point by paying a $555 fee in an attempt to extend a patent held by the inventor, who wanted it to lapse. Gun manufacturers said the technology was expensive and ineffective, and a National Rifle Association lawyer has threatened a lawsuit.
