California's Firearm Registration

California does not record the serial numbers of guns only the sale. Technically there is no law that firearms owned before the Department of Justice’s Automated Firearms System was created. However there are penalties for not registering previously owned firearms with the Department of Justice’s Automated Firearms System.


§12025 and §12031
