I'm working on a pig hunt for sometime in January, the number for California fish & game is 916-928-5805.I do know you need a license and a pig tag,fish & game said there is no bag limit. Then I asked about handguns,they have to be centerfire with a barrel of 4" min. so my 7.5" will be good.An out of state lic. is around 137.75 pig tag 63.50. Its about 201.25 total. They also have a web site that I don't have handy.Good luck, let us know what you find out.
