Legal Question in Criminal Law in California

If, as part of that case, you had imposed against you a DV restraining order, which would be normally imposed in that kind of case, you would be barred for life from owning, possessing, or having under custody or control, any firearms or ammunition. You could not touch a firearm ever again. The same applies for any felony conviction or mental facility involuntary commitment.

If the misdemeanor was one of a long list of those involving weapons or threats or stalking, it could have carried a 10-year ban on firearms. In the case of a 10 year ban, as implied in your text, rights would be restored 10 years post conviction.

You should verify the facts by reviewing the criminal court file and the sentencing orders on the case, before you apply to buy a firearm. If you are barred from firearm possession, then simply applying to purchase one would be considered a new felony.
