  • 9×19mm Parabellum

    serch.it?q=9×19mm-Parabellum

    The 9×19mm Parabellum is a firearms cartridge that was designed by Georg Luger and introduced in 1902 by the German weapons manufacturer Deutsche Waffen und Munitionsfabriken (DWM) (German Weapons and Munitions Factory) for their Luger semi-automatic pistol. For this reason, it is designated as the 9mm Luger by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI), and the 9 mm Luger by the Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives (CIP). The name Parabellum is derived from the Latin: Si vis pacem, para bellum ("If you seek peace, prepare for war"), which was the motto of DWM. Under STANAG 4090, it is a standard cartridge for NATO forces as well as many non-NATO countries. According to the 2014 edition of Cartridges of the World, the 9×19mm Parabellum is "the world's most popular and widely used military handgun and submachinegun cartridge." In addition to being used by over 60% of police in the U.S., Newsweek credits 9×19mm Parabellum pistol sales with making semiautomatic pistols more popular than revolvers.

  • Overpressure ammunition

    SPEER GOLD DOT 124gr 9mm+P in SIG P226 MagazinesOverpressure ammunition, commonly designated as +P or +P+, is small arms ammunition that has been loaded to a higher internal pressure than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round. This is done typically to produce rounds with a higher muzzle velocity and stopping power, such as ammunition used for defensive purposes. Because of this, +P ammunition is typically found in handgun calibers which might be used for defensive purposes.

    Cross-section of a hollow-point bullet.Proportions are those of a .22 Long Rifle cartridge. .357 Magnum rounds. Left: Jacketed soft point (JSP) round. Right: Jacketed hollow-point (JHP) round. JSP is a semi-jacketed round as the jacket does not extend to the tip. Various hollow points: .45 Auto, .38 Special, .44 S&W Special, .44 Remington MagnumA hollow-point bullet is an expanding bullet. It is used for controlled penetration, where over-penetration could cause collateral damage (such as aboard an aircraft). In target shooting, they are used for greater accuracy and reduction of smoke, fouling, and lead vapor exposure, as hollow point bullets have an enclosed base while traditional bullets have an exposed lead base. Plastic-tipped bullets are a type of (rifle) bullet meant to confer the aerodynamic advantage of the spitzer bullet (for example, see very-low-drag bullet) and the stopping power of hollow point bullets.
