I could be WAY off but if its just a 1911 you shouldn't be breaking any CA laws... unless you've made modifications that might break CA laws. Sadly CA has a lot of stupid laws regarding firearms so if its just a basic 1911 I'd say you're safe. If not and you've got some exotic modification on it check the laws carefully.
Actually I just chuckles a bit thinking about it - a Para 1911 with the 14rd double stack mag with a threaded barrel for a suppressor. Cross the border with that and you'll set off red lights and sirens all over CA! lol!
This is who we are, what we do.
