The .380 ACP is a type of 9mm... 9x17, and is sometime referred to as the 9mm Short or 9mm Kurz. It is NOT the same as the 9mm Luger/Parabellum (9x19), and it is NOT compatible with any other type of 9mm cartridge (such as the 9x19 Luger/Parabellum, 9x18 Makarov, 9x21, 9x23, 9x25, etc.).
The .380 is a 9mm bullet. But, going with the assuming that you're comparing the .380 ACP (9x17mm) against the 9mm Luger/9mm Parabellum (9x19mm), the answer would be no.
380 and 9mm ammunition IS NOT INTERCHANGEABLE.
Roughly .35--.36 caliber.
They use bullets of the same diameter, but with different weight ranges, which happen to overlap. The .380 uses a 9mm diameter bullet in a 17mm long case. The 9mm uses a 9mm diameter bullet in a 19mm long case.
9mm and .380 bullets are the same diameter. In fact, .380 is also called 9mm Kurz(short) or 9x17. However, the caliber commonly called 9mm is 9x19, which means the cases are different size. A .380 cartridge will fall down into the chamber and the firing pin will not reach the primer. So, a .380 bullet can be fired from a 9mm gun if it were loaded into a 9mm case. A .380 cartridge would fail to fire in a 9mm gun.
No. The diameter is the same, but the bullets still differ in length and weight.
No, the bullet will not seat.
380 and 9mm projectiles are .355 in diameter _________________________ Most of the time, when people use the term 9mm, they are referring to a 9mm parabellum. A 9mm parabellum cannot be fired from a .380. The 9mm cartridge is longer. _________________________ The BULLET is the part of the cartridge that is the projectile. While 9mm parabellum and .380 ACP use the same diameter bullets, the CARTRIDGES are not interchangeable.
The 380 ACP, also known as the 9mm Short, 9x17, 9mm Browning, 9mm Kurz and 9mm Corto uses a .355 diameter bullet. The 38 special uses a .357 diameter bullet. Additionally, the 380 ACP is designed for a semi-automatic and the .38 special is designed for a revolver.
None, the projectile diameter is the same for both - .355. If you are asking about a complete round of ammunition, the 9mm case is 19mm long and the 380 case is 17 mm long. This cartridge is called the ".380 Auto" for use with an automatic pistol. However, the most common 9mm round is the "9mm Lugar". This cartridge has a heavier bullet and a longer case, thus a larger muzzle velocity and energy than the .380 Auto.
No it is dangerous to attempt a 9mm is a bigger bullet. More specifically, 9mm Luger is a longer cartridge that .380 ACP.
It depends on what you mean exactly. 380 is a bullet that is 9mm in diameter, but it is not the same as what most people mean when they say 9mm. Usually, at least in the U.S. the term 9mm refers to 9mm para which is 9x19. A 380 cartridge is 9x17, so it is shorter. It may be possible to fire a 9x19 cartridge out of a 380 gun, but it is a bad idea because it is too long, and because it is a much higher pressure cartridge.
