9MM Ammo For Sale!
After World War I, acceptance of the 9×19mm Parabellum cartridge increased, and 9×19mm Parabellum pistols and submachine guns were adopted by military and police users in many countries. The 9×19mm Parabellum has become the most popular caliber for U.S. law enforcement agencies, primarily due to the availability of compact pistols with large magazine capacities that use the cartridge.
From the early 1980s to the late 1990s, a sharp increase occurred in the popularity of semi-automatic pistols in the U.S., a trend foreshadowed by the adoption of the Smith & Wesson Model 39 by the Illinois State Police in 1968. In addition, the Beretta M9 (a military version of the Beretta Model 92) was adopted by the U.S. Army in 1985. Previously, most American police departments issued .38 Special caliber revolvers with a six-shot capacity. The .38 Special was preferred to other weapons, such as variants of the M1911, because it offered low recoil, was small and light enough to accommodate different shooters, and was inexpensive. The 9×19mm cartridge is ballistically superior to the .38 Special revolver cartridge, is shorter overall, and being an autoloader cartridge, it is stored in flat magazines, as opposed to cylindrical speedloaders. This, coupled with the advent of the so-called "wonder nines", led to many U.S. police departments exchanging their revolvers for some form of 9mm semiautomatic handguns by the 1980s and 1990s.
