A police chief in Texas once told me that the 9mm cartridge was the water gun of the firearms world. He explained that in his experience a 9mm at point blank range was as capable of stopping a determined aggressor as a fly was at stopping an 18 wheeler; whereas, the .45 ACP just about always takes the fight out of an aggressor immediately.
The M45A1 Close Quarters Battle Pistol (CQBP) was decided on July 20, 2012, from three submissions to a 2010 solicitation handed down by Marine Corps Systems Command (MARCORSYSCOM). Colt, Springfield Armory and Karl Lippard Designs each offered Leathernecks a replacement for the age-old rebuilt .45s. A variation of the 1911 Rail Gun won and re-upped Colt’s enlistment in the U.S. Marine Corps.
The original 1911 and 1911A1 were the workhorses of the battlefield in their extensive service over much of the 20th century. The 1911 served U.S. soldiers in two World Wars and several other major conflicts, and all the while provided reliable stopping power that could be counted on in the time of need.
