Preview:

The 9mm Luger cartridge is flawed. It has been flawed since its development around 1902 by Georg Luger for his famous Luger pistol. Since then the 9mm Luger (also known as the 9mm Parabellum, 9X19, 9mm NATO or just the 9mm) has become one of the most popular cartridges on the planet. It is chambered in handguns, submachine guns and rifles, and is the standard NATO round for handguns. Frank Barnes (2006) notes that it is the most widely used cartridge in the United States.

The 9mm Luger has become especially popular for small, compact carry guns intended for self-defense. It is a potent cartridge for its size and offers good performance with well-designed bullets.

But the cartridge has a troubling flaw. It’s tapered. 

Taper increases a problematic behavior called nosedive. Nosedive occurs when the nose of the cartridge cams downward while being pushed forward out of the magazine during feeding. This causes the bullet nose to hit low on the feed ramp and at a more perpendicular angle. A tapered cartridge exacerbates nosedive, and the more a cartridge nosedives, the more likely it will cause a feeding malfunction.
