Query: This Book is a Badly Needed Reality Check.

This book is a 300lb counter-balance to gun magazine fluff. Mr. Thomas does a nice, rather entertaining job of bursting our collective bubble on the effectiveness of handgun cartridges. He lets us know that many different types of handguns may indeed be suitable for self-defense though are favorites certainly aren't perfect. And, that handguns just aren't very effective at stopping a determined attacker. I wish more people in the gun community had the more realistic perspective offered by this book. -- An intelligent and entertaining read.If you are looking for another reality check, consider Guns Save Lives by Roger Waters.
