When you think about the venerable 45 ACP, many synonymously associate it with the 1911, and rightfully so. That dynamic duo has planted many freedom seeds and fertilized the ground with many enemies over the hundred plus years it has served this Nation.
Born in 1904, and put into full production in 1905, the 45 Automatic Colt Pistol (45 ACP) is a rimless straight walled handgun cartridge, designed by John Moses Browning as an answer to the military’s cry for more “stopping power.”
During the first decade of the 1900s, the Army was engaged in a conflict with a group of natives that tourniqueted their appendages and took a substance to limit the pain from potential injuries. This meant the meager 38 S&W that was the standard issue side arm cartridge at the time was not hitting with enough “umph.” Thus, the contract went out to find a round and firearm that would put down a threat with more “authority.”
Once the 45 ACP rolled out in 1905, Mr. Browning began optimizing the platform that would later be known as the 1911, a design that would be the side arm of Freedom for decades to come.
45 ACP has been a staple cartridge for American households since its inception and adoption. It is this infamy that many still carry this venerable cartridge for their own protection! Here are a few of the best rounds for self defense:
