Yes - FFL transfers are legal
If you _really_ shop around, you may be able to find a transfer
agent that will do it for around $25 (including DROS). They will
typically charge you CA sales tax on the transfer even for out of
state sales (which seems a little suspicious to me).
More commonly, it will run you $35 for FFL (not including DROS)
and shipping ($20). You would have to pay the DROS and tax
anyway, so if you can save $55 off the local price, it is probably
worth the effort.
I was under the impression that the FA63 wasn't nearly as
comfortable and reliable as the Mak. For $200, it would probably
be worth spending a little more and getting a CZ83 or a Bersa.
