The 9×19mm Parabellum (also known as 9mm Luger, 9mm NATO or simply 9mm) is a rimless, centerfire, tapered firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, [ 6 ] it is widely considered the most popular handgun and submachine gun cartridge due to its low cost, adequate stopping power and extensive ...
9mm Major is a wildcat cartridge of the 9mm Luger specifically for competition pistols designed to handle very high pressure. It is used in practical shooting competitions like International Practical Shooting Confederation (IPSC) and United States Practical Shooting Association (USPSA) to achieve a "Major" power factor, which earns more points for hits in specific zones on paper targets ...

Adopted in 1912, the 9mm Steyr was the service ammunition for most branches of the military in Austria-Hungary during World War I and remained the service ammunition for Austria, Romania and Chile between the World Wars. [2] Some MP 34 submachine guns were also issued in this caliber in addition to 9×25mm Mauser.
Around 1987, Randy Shelley, an employee of Dillon Precision, necked down 10mm Auto brass to 9 mm. His goal was to get as much slow-burning powder in the case as possible in order to drive a 9 mm bullet to the velocity needed to qualify for the then-IPSC major power factor of 175.
This is a list of firearm cartridges that have bullets in the 9 millimeters (0.35 in) to 9.99 millimeters (0.393 in) caliber range.. Case length refers to the round case length.
The 115 gr (7.5 g) 6.8-round has a higher muzzle energy of 1,694 ft⋅lb (2,297 J) due to its greater velocity, while the 125 gr (8.1 g) 300 BLK round has a muzzle energy of 1,360 ft⋅lb (1,840 J). Both rounds were made to be used in an easily converted AR-15 .
Let m b and v b stand for the mass and velocity of the bullet, the latter just before hitting the target, and let m t and v t stand for the mass and velocity of the target after being hit. Conservation of momentum requires m b v b = m t v t. Solving for the target's velocity gives v t = m b v b / m t = 0.016 kg × 360 m/s / 77 kg = 0.07 m/s = 0 ...
