Help with morass of state gun laws

First: I am not a lawyer. Nothing I post here is to be regarded as legal advice.

That said, there are a few websites that you can look at:

http://en.wikipedia.org/wiki/Gun_laws_in_the_United_States_(by_state)
http://www.gunlaws.com/links/

These are just a few. There are many more. The first one is the main one I use regularly.

This website is one place I normally start when looking to travel with a firearm. (Rail beat me to it...those are all fantastic links)

If you can spare $30.00, get a C&R license. You can buy any gun over 50 yrs. old, mailorder, without a waiting period and blah, blah, etc. But along with this license you will recieve a book listing all the federal firearm laws, and a book listing all the individual state firearm laws. And by "listing", I mean the full text of all the laws (except state's wildlife/hunting codes).
It is well worth it for the legal information alone. But you will buy C&R eligible guns once you get it. You won't be able to help yourself. Intergooglenet C&R guns for sale. (AuctionArms, Gunbroker.com, etc.) Do it, you won't regret it.

Looking at your list I would say your good to go in Arizona but the People's Republik of California is pretty much out of the question.

You might want to try "Traveler's Guide to the Firearms Laws of the 50 States".
It is written by an attorney and is updated for 2010.
