You usually have to show proof of residency when purchasing firearms and my only valid driver's license is for CA. My utility bills, vehicle registration, etc, are all CA. IF you purchased a non-roster handgun BEFORE moving to California that would be fine, but if you are a legal resident of California you can not go across state lines and bring in a non-roster handgun - its all about when you acquired the handgun and whether you were a CA resident at that time. If you live in CA but have another state's DL to show residency in that state then you COULD do it, but in CA, the DMV requires changing of DL to CA if you stay beyond 20-days (I think ... that was many years ago when I first moved to CA). I'm not well versed on CA DOJ regulations so please do not take what I say as gospel - some of the wording is a little vague and open to some interpretation and I am not trained to inteprete any of it!
Its not impossible to obtain a non-roster handgun, but its a sticky area and something I don't want to test. I am completely fine with the SP01, although the Shadow already has many of the upgrades I would like to get, plus an additional magazine. What I would really have liked that's not available on the SP01 is the deeper cuts on the trigger guard and beaver tail. I could get it machined on the SP01 but then I'd have to have it refinished, etc. Not sure if its worth it or how much difference it would make for me.
Poor me ... I'll just have to do with the lowly ol' SP01 (that was typed with a lot of sarcasm in my fingers

).
Going tomorrow to fill out the DROS, then its a 10-day wait before its in my possession.
