The included Web site, is one of some very good reference material, that is available on topics of great interest to us, the Gun Community.
I have had the book The Second Amendment Primer, by Les Adams, for a long time now, it was given to me by an co-worker, after one day on the job, during a heated argument at lunch, over the meaning of the Second Amendment, Personal Right, or only a Militia right.
At any rate, the person that gave me the book, said all you need to know about the 2a is in this book, keep it, and walked away.
This book and others are available here.
