Homemade handguns illegal in 2015?

[rromeo]

With the end of the SSE in sight, does this mean that next year there will be no legal way to manufacture a homemade handgun in CA (e.g. from an 80% 1911 receiver), since any homemade handgun cannot be previously listed on the roster, and therefore would have to be considered an "unsafe handgun"?

If so, would it be legal to finish the machining of an 80% receiver *outside* of CA (e.g. AZ, international waters, etc.) and then import the finished gun into CA the next day? My understanding is that the importation of unsafe handguns is legal, so long as they are for your own personal use and they are not otherwise illegal, correct?

It is still legal I think. Your 80% 1911 was never a semiautomatic pistol, so you didn't convert it to single shot, then convert it back. You would make a single shot pistol, then convert it to semiautomatic.
