Legal Question in Criminal Law in California

If you have been convicted of a felony, you are now a 'prohibited person' who may not own or possess firearms or ammunition. You must immediately get rid of any firearms legally, by sale or transfer, and keep written proof of that, such as dealer record of transfer. It would be unwise to have any firearms or ammunition in your residence even belonging to any one else.

You cannot keep a firearm, once you have been convicted of a felony, regardless of whether it was a "nonviolent" felony or not. Mr. Nelson is correct, in that you need to contact a firearm dealer, and sell them immediately, and keep proof that you no longer have them. You do not want to be caught with the thing after conviction, as it would constitute another felony.
