I'm very impressed with this book, as well as Max' first book, "Big Bore Revolvers". Covers Ruger's history, the old guns, the new guns and everything in-between. Great section on custom Rugers as well. First book was paperback only but the new one is a hardcover and all pictures are in color. Highly recommended reading for you revolver shooters.
