edit Production History
The .38 Special was introduced in 1898 as a military service cartridge as .38 Long Colt had insufficient stopping power against the wooden shields of Moros during the Philippine-American War. The .38 Special rounds can be fired from revolvers chambered for .357 Magnum or the .38 Long Colt as only the case length of .38 Special is different. But a .357 Magnum is more powerful and cannot be fired in a revolver chambered for .38 Special. The 9mm Luger was designed by George Luger from his earlier 7.65X21mm Parabellum. In 1902 he presented it to British Small Arms Committee. In 1903 he presented 3 prototypes to the US Navy. It was adopted by the German Navy in 1905 and the German Army in 1906.
Initially, .38 Special was introduced as powder cartridge and then was manufactured as smokeless powder loadings as a result of its popularity. Initially the 9mm Luger was lead core. But during WWII to conserve lead, it was made using iron core jackets. By 1944, normal copper core cartridges were produced.
.38 Special were popular among the US police and was used by the US Air force, Navy and the Marines. But their popularity has declined due to the higher capacity and quicker reloading of semi-automatic pistols in the 9mm Parabellum, the .357 SIG, the .40 S&W, the .45 ACP, or the .45 GAP versions. .38 Special is used for target shooting, formal target competition, personal defense, and for hunting small game.
9mm Luger has become the popular caliber for US law enforcement agencies due to the availability of compact pistols with large magazine round capacity using this caliber. It is also a popular self-defense cartridge for civilians where permitted.
Ammunition in 9mm is available in bulk and has many variations than the ammunition for .38 Special. It is also cheaper.
