Number of Concealed Carry Permits by County in California
With Governor Jerry Brown signing a law that banned the open carry of unloaded guns, in some counties people are effectively banned from carry a gun for protection in any way. For example, no civilian in San Francisco has a concealed handgun permit. In Los Angeles, only 220 people have permits. Relatively rural Kern county has given out 3,789 permits.
