Principles Of Personal Defense
This is one of Colonel Jeff Cooper's classic works, in a new third edition, with a new Foreword by Louis Awerbuck. It's an oldie but goodie, first published in 1972.
I'm sure most of the old (did I say "old"? I meant "experienced" or "seasoned") hands on the forum own or have read this book, but maybe some of our younger members, or those new to shooting, haven't read it. Heck, there might even be some who have never even heard of Jeff Cooper.
Anyway, I highly recommend it. It's sold by www.paladin-press.com.
