The Model 1911 was the product of a very capable person, namely John Moses Browning, father of several modern firearms. The pistol was designed to comply with the requirements of the U.S. Army, which, during its campaign against the Moros in Philippines, had seen its trusty .38 revolver to be incapable of stopping attackers. An Ordnance Board headed by Col. John T. Thomson (inventor of the Thomson sub-machine-gun) and Col. Louis A. La Garde, had reached the conclusion that the army needed a .45″ caliber cartridge, to provide adequate stopping power. In the mean time, J. Browning who was working for Company, had already designed an autoloader pistol, around a cartridge similar to contemporary .38 Super (dimension-wise). When the Army announced its interest in a new handgun, Browning re-engineered this handgun to accommodate a .45″ diameter cartridge of his own design (with a 230 gr. FMJ bullet), and submitted the pistol to the Army for evaluation. This is a gas gun, which means it’s powered by gas and doesn’t need to be cocked every time. It’s fast, clean, inexpensive and easily maintained; it does not require batteries to operate.
