Actually Vapodog, I think you may be confused as to the weapon and cartridge I am talking about. The M-1 was introduced to provide certain troops with a lighter easier to carry weapon than the Garand. The M-1 .30 carbine had miserable stopping power and not much better accuracy. That' s why it has been relegated to plinking duties, whereas other military weapons are either still in service, or have found second lives as hunting rifles. I am talking about the .45acp in a 1911 auto. This round was in service for nearly 50 years, from WWII until the 1980' s when it was replaced by the Baretta 92 in 9mm. Even though it is not the official issue, it is still carried by some SF units and other law enforcement units. Some use their own money to purchase them because of the reknowned stopping power of the .45acp. The stopping power of the .45 in a 1911 type pistol has never been in question. At least not on the 2 legged prey. I feel pretty confident that within certain situations it will be effective on game of the 4 legged kind too.
