I had a copy of his book but it disappeared in a move years ago. It was quite interesting, but of course was just one man's opinion based on his rather limited experience. (Shooting caribou with a 10" XP in .221 Fireball was a stunt, not really handgun hunting....IMO anyway. He had much more appropriate handguns along.)
That said, the book was great reading and a wonderful historical document on the early days of the hobby. Along with Keith's writings, Goerg had a huge impact on the sport in its infancy. I remember reading a piece in GUNS(?) describing his conversion of an XP to 6mm Remington with laminated stock, along with chronographed ballistics. That article stuck with me for years and had a big influence on my handgun tastes later in life. Perhaps you could find a used copy of his book on eBay or Amazon.
