I think this might become a must have series. The only problem I can think of is I think the author would get better use out of using dots (either reflecting Resources/Contacts to obtain) instead of MSRP. It is a nitpick, and one that is easy to overlook. I learned a few things about guns, and I have effectively owned two versions of this book for different systems. The author strove for updated information and accuracy, and it really shows.
