MRpink, I would go with the 10/22 out your choices because there are so many parts and options out there for them. Another thing is the Sig might not be CA DOJ compliant since it is supposed to have a folding stock, removable magazine, flash hider, etc, and it would have to pass the drop test. Look into the laws there but that is what a friend of mine that is stationed out there was telling me.

Men you can't trust, women you can't trust, beasts you can't trust, but Bussekin steel you can trust
