People who have been convicted of a felony in Nevada are no longer allowed to own or possess guns. The only way they can get their gun rights restored is to receive a pardon from the Nevada government.
Note that pardons do not seal the felony conviction. Also note that pardon applicants have to specifically ask for gun rights to be restored…otherwise, the pardon will restore only a person's civil rights such as to vote and serve on a jury.
The Nevada Board of Pardon Commissioners meets at least twice a year to consider pardon applications. Only convicted felons who are no longer serving their sentence may apply for pardons. Furthermore, it's advised that applicants wait a “significant period of time” before submitting a pardon application in order to show that they have been fully rehabilitated. (Note that people convicted of misdemeanor battery domestic violence may apply for pardons as well.)
The government grants very few pardons, and it typically does not allow rejected applicants to reapply. Therefore it is recommended that applicants retain counsel to compose the pardon application. Call the Nevada Pardons Board at 775-687-5049 for an application. Learn more about Nevada pardon laws and the Nevada definition of deadly weapons.
