A Brief History of the 10mm Caliber
The origins of the 10mm caliber can be traced back to the late 1980s when renowned firearms designer Jeff Cooper envisioned a powerful cartridge that could bridge the gap between the .45 ACP and the .357 Magnum. Cooper, known for his expertise in firearms and his influential writing on the subject, sought to create a cartridge that offered improved performance and stopping power.
In collaboration with Colt's Manufacturing Company and Federal Cartridge Company, Cooper developed the 10mm Auto cartridge, initially known as the 10mm Norma. The cartridge was designed to be used in semi-automatic pistols, offering a balance between the stopping power of larger calibers and the controllability of smaller ones. The 10mm Auto quickly gained attention and became a sought-after choice for law enforcement and self-defense applications.
