Technically it's possible to get up to 1 year in jail, 5 years of probation, with other mandatory probation terms, including a 52 week domestic violence class, fines, and a 10 year firearm prohibition. What you end up getting depends on the judge, your lawyer, and how the facts of the case come out, among other factors.
In addition to the penalties above, you may lose your California Professional License, have a presumption against you for Child Support and will never be able to own a firearm or possess a firearm.
