In general, all sales from out-of-state to California need to go through a 01-FFL (that's a normal gun dealer, not a C&R 03-FFL). And in general, the handgun roster does apply. There are exemptions for transfers between parent and child, for roster-exempt guns (like olympic target pistols and single action revolvers), and roster-exempt buyers (like LEOs). But in general, the roster applies to importation into the state, which includes the case of a private party from out of state selling to a FFL in the state.
I don't remember whether there is an exemption for sales directly to a 03-FFL or a C&R-eligible handgun or not. Since they are exempt from the roster anyway, one could always process that one through a normal gun store (01-FFL) anyway, except for little things (ha ha) like the 10-day wait, the 30-day limit, the fees, the paperwork, the hassle, and so on.
EDITed to add: Never mind, saw in another thread: the 01-FFL is actually the end user. That completely changes things; all the above answers are for a regular person buying from out of state, and processing through a 01-FFL.
