Legal Question in Criminal Law in California

NO. Passage of time and successful programs or probation have nothing to do with it. Conviction of ANY felony, and most domestic violence misdemeanors, makes you a person prohibited for life from possessing any firearms or ammunition. To be found in such possession would be a new federal and state felony. Only a full Governor's pardon including full restoration of firearms rights could potentially restore your rights. Successfully obtaining one would require an overwhelming showing of factual innocence of the charge or other basis sufficient to overturn a wrongful conviction that 'offends the conscience'. That is not what you described. Nor would the Governor overturn a plea bargain conviction. The best you can accomplish is to Petition to expunge the conviction so you don't have to report it on most employment applications. If serious about doing so, feel free to contact me to discuss.
