I see that he is from California, so by buying from you, has broken their laws that are so restrictive that many manufactures have left, and those who are not in that State won't deal with them. Handguns even have a separate section of laws. Used guns are listed, those on the list supposed to have been tested, if they are not on the list then they can't be sold. All firearms must be FFL tranfered or sold, as is ammo through an FFL. All requires background checks. Even if legal, I would find out your State laws and deal with that. All out of state sales FFL to FFL buyer pick up costs.It depends on your State laws. If it is not against the state law for person to person it's likely OK. Up to you to check and it can be found out by a FFL Dealer in your State. Remember if you sell to anyone, the responsibility you will wear if the firearm is used in a crime and bought through a FFL Dealer, you are still the owner.
