We have also been advocates for “The Traveler's Guide to the Firearm Laws of the Fifty States.” I feel it is the most complete and also simple firearm law book available on the market. The 2016 edition is the 20th edition of the book which is written and published by Attorney J. Scott Kappas.
Each state of the fifty states has a SINGLE PAGE summary of all the gun laws you need to know about when you travel to that state. It couldn't be easier to use.
Considering the legal issues that gun owners encountered last year in 2015 when they unknowingly broke laws in New Jersey, Texas, California, New York, and Kentucky while traveling there, I think its more important than ever that we have a resource that is simple and available.
Of course, we wouldn't need a book like this if Washington would just pass some legislation that would give gun owners universal and easy to understand rights when traveling but since that isn't likely to happen anytime soon I'll settle with this book.
Also if you click on the above link there is a place on that page where you can get a sample page of the book so you can have a sense of the layout.
