Regarding SIG availability and external safeties, since Glocks and Walther P99's have passed certification, I'm hoping SIGs will, too.
Regarding what is a 'safe' in Kalif., actually it also won't include whatever handguns not submitted for testing and certified. So part of the effect is that, unless the big name custom gunsmiths are going to pay the fees and submit so many test guns per model for testing/certification, some the highest quality and most expensive custom guns will no longer be available for sale either. I doubt the one or two man custom 1911 shops are going to bother or can afford to comply, even if they were inclined to...
So far nothing in the 'junk gun' law involves confiscation of what is already owned.
As far as moving into Kalif., I believe what handguns you have is grandfathered in (not so with assault weapons!)
You will have 'register' them though...
Info on Report of Handgun Ownership form that must be filled out for new Kalif. residents (plus $14 fee PER handgun) within 60 days, another stupid new law... (ripoff!)

(gee, I feel safer already...)
You may be technically SOL with the hi-cap mags. My understanding that they would have to been in the state as of 1/1/2000 to be grandfathered. You might want to go below and do a text search on 'magazine' to double check.

Of course, them proving it would be another story...
It is okay for Kalif. residents to leave the state with hi-caps and come back with them (import) as long as the mags were owned within the state before 1/1/00...
