A felon can in some cases own a gun in California after 10 years.
However in California being a felon and having a felony conviction often leads to a lifetime ban on owning guns and firearms.
However you can go through some avenues to possibly restore your gun rights as a felon after 10 years including through a gubernatorial pardon or court order.
California is often pretty strict on felonies and gun ownership or firearm ownership and they often band a person for life from owning a gun or firearm when convicted of a felony.
People who want to restore their gun rights after 10 years after a felony conviction may be able to do so by successfully completing parole or probation, showing exemplary behavior and not committing any further crimes.
A court order can also restore a felons gun rights if the felon is currently employed by the state of California and their job requires them to own or possess a firearm.
And a gubernatorial pardon can restore a felons gun rights in California.
However an expungement or sealing of a felony conviction does not restore gun rights.
It is possible to restore your gun rights as a felon in California but it's not an easy task.
Even having certain misdemeanor convictions in California such as domestic battery, battery or assault can lead to a 10 year ban on gun ownership.
