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.
You can only use .380 ACP ammo in a .380 pistol. Period.
Depends on which 9mm you are refering to
380 aka 9mm Kurz ammuntion only. BTW, the 380 and 9mm use the same size projectile. Difference is the case length.
9mm and 380 both use bullets with a diameter of .355. But the answer to the question you're probably asking is, no, you cannot fire a 9mm parabellum cartridge from a .380 handgun. The 9mm cartridge is different than the .380 cartridge. Even though both are 9mm in diameter, the overall cartridge lengths are different.
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 both use bullets with a diameter of .355. However, the cases are a different size. .380 is also known as .380 auto, 9mm Kurtz, 9mm Corto, 9mm short or 9x17. 9mm typically refers to 9x19mm also known as 9mm Parabellum or 9mm Luger. You cannot fire a 9mm Parabellum cartridge from a .380 handgun. The 9mm cartridge will not fit into the chamber of the gun. However, if you were to pull the bullet out of the .380 case and put it into a 9mm Para case the resulting cartridge will work just fine.
No firearm exists that can shoot both 380 and 9mm. Unlike, say, the 357 magnum which can shoot 38 specials. Revolver rounds use the case rim to assure proper head space so they are more interchangeable. The 9mm and 380 are made for auto-loaders and they use the case length, rather than a rim, to determine proper head space. Because of that you can't shoot a 380 through a 9mm.
Most are in .380 ACP caliber. Sometimes called 9mm Short in Europe (or 9mm Corto or 9mm Kurz) What is marked on yours?
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.
Yes, there are. There are different 9mm Cartridges, and different 9mm bullets (bullets being the part of the cartridge that comes out of the barrel. Some of the different cartridges are 9mm Parabellum (the everyday 9mm) 9mm Browning Long, 9mm Magnum, 9mm Largo, 9mm Kurz (the .380) 9mm Makarov and a dozen others. 9mm BULLETS may be different weights, slightly different sizes, and may be round nosed, hollow point, truncated cone, tracer, etc etc.
The .380 automatic cannot shoot 9mm Parabellum ammo.
Assuming you're referring to the 9x19mm (also known as the 9mm Parabellum or 9mm Luger) and the .380 ACP (also known as the 9x17mm, 9mm Short, and 9mm Kurz), the answer is no on both counts, and it would be extremely dangerous to try this.
