The 9 mm Parabellum is the most widely used handgun cartridge in the world. Many military personnel, law enforcement officers and private firearms owners use it. This cartridge is not strictly used in handguns; several different styles of guns, both large and small, fire the 9 mm Parabellum cartridge.
Short pistols featuring 9 mm cartridges are extremely common, having replaced the Colt .45 models as standard-issue military sidearms. They are relatively low-powered and easy to handle, with a manual slide that locks the hammer into place and chambers a round in the barrel when cocked. Famous models of short pistols include the Browning Short, the Glisenti, the Luger and the Makarov.
The higher muzzle velocities of long pistols, combined with their heavier weights, give them more power when fired -- at the expense of greater recoil. Long pistols are less common in military and law enforcement ordinances but are frequently seen in movies, as their greater size gives them a fearsome appearance. Notable 9 mm long pistol models include the .357 SIG, the Magnum, the Steyr and the Mauser.
Revolvers are repeating-fire weapons with cylindrical chambers designed to move the next cartridge into firing position by rotation. These were in common use in the late 19th and early 20th centuries and remained in use in later decades in Eastern Europe. Noted revolvers that use 9 mm rounds include the .38 Long Colt, the .357 Smith and Wesson Magnum, and the Remington Maximum.
The idea of pistol rounds being used in rifles might seem counterintuitive, but several rifle models use 9 mm cartridges. Many are shortened versions of established models, such as the Colt Model 635. Introduced in the 1990s, these rifles are essentially modified versions of the M16 rifle, designed to be legal for civilian use. Other models using 9 mm cartridges include the .35 Winchester, the .35 Remington and the .376 Steyr.
