"I will be traveling to California and want to carry my weapon. I currently have a concealed weapon permit. How can I legally transport my weapon while driving through the state?
California law does not recognize concealed weapon permits from other states; therefore, they would not be held valid. If you wish to transport a handgun during your California visit, it should be carried unloaded in a locked container. In the absence of a suitable container, you may secure the unloaded handgun in the locked trunk of a passenger car. Ammunition may be kept in the same container or trunk, but the handgun must remain unloaded with no rounds in the cylinder and no loaded magazines in the magazine well."
