Firstly, General Geoff's post above is a bit unclear. What needs to be said is that hicap *magazines* can't be shipped into CA - guns that use them certainly can be. (Exception is no AWs - which for pistols means nothing like a Tec9 or HKSP89, or any semiauto pistol that has a threaded bbl. Careful, as quite a few comped pistols may have threaded bbls under the comp/muzzle weight. Browning HiPower GP competition is one example.)
Californians cannot import handguns that are not on the state-approved Roster (drop tested, etc.) - however, single-action wheelguns and single-shot pistols are exempt if dimensionally compliant.
Even non-Rostered handguns can be inherited from within or outside of CA. They can also be transferred inside or from outside CA between grandparent, parent, child, grandchild (the only authorized relationships in the 'interfamily transfer' law; nephews *not* included). Noninheritance interstate transfers would require services of an FFL dealer.
BTW "willing" & "inheritance" concept does NOT include, "I'm old & sick so I'm giving that young whippersnapper my guns." It only means the person who's willing the guns actually kicked the bucket and his estate is being properly disposed of.
If the handguns are not Rostered, Carolina dude can't give CA nephew the guns. He can only do this either:
(1) if he kicks the bucket and probate is active, or
(2) somehow legally gives the guns to CA dude's father or grandfather (or, remotely, son or grandson), who then transfers gun to CA dude.
I believe no FFL is actually required for *inheritance* guns (as opposed to 'gifted' guns between family members.) To be safe, have 'em shipped to a CA FFL the California guy picks out.
The CA recipient must:
(1) not be a prohibited party (i.e, nonfelon, no violent misdemeanors, etc.)
(2) hold a valid HSC (Handgun Safety Certificate) card: it costs $25, good for 5 years, and requires the applicant to answer approx 15 or 20 (?) simple multiple-choice gun safety questions.
(3) if not going thru FFL if this is a true probate/inheritance situation, recipient must file papers w/Calif DOJ ("Firearms Acquisition thru Operation of Law" form). There's a $19/gun fee last time I checked; form is avaliable on Calif DOJ Bureau of Firearms website.
