Since gun manufacturers are not likely to spend money retrofitting their entire production lines, California has effectively banned the sale of all new guns.

 

The law, which was initially signed back in 2007 by then governor Gov. Arnold Schwarzenegger, was delayed because of patents on the technology. On Friday, the Attorney General of California certified the law, becoming the first state in the country to require new guns use this stamping technology.

The “microstamping” act requires every new handgun produced or brought into the state of California to have a special firing pin that will stamp a serial number onto the primer of a round.
