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.
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.
No it is dangerous to attempt a 9mm is a bigger bullet. More specifically, 9mm Luger is a longer cartridge that .380 ACP.
No, the calibers and chamberings are completely different. It is not safe to attempt to fire any caliber of ammunition in a gun, other than what is stated on the barrel. actually the 380 caliber is almost equal to the 9mm. the 380 caliber is often refered to as a 9mm short. the difference is the 9mm case is slightly bigger then the 380 case and the 380 bullet might be a little lighter.......................
380 and 9mm ammunition IS NOT INTERCHANGEABLE.
.380 ACP is 9x17mm. That's the only cartridge that gun can fire. 9x19mm (a.k.a., 9mm Parabellum or 9mm Luger) and 9x18mm (a.k.a., 9mm Makarov) are NOT compatible with these guns.
NO!! Although the bullet diameter is the same, the case length is different and should not chamber in the 380 caliber handgun.
About .36 caliber. The 9mm family of calibers normally uses a bullet that is .356 diameter. This is the same as the .380 and nearly the same as the .38 Special, whose "nominal" calibers are quite different from their actual bullet diameter when measured.
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.
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.
Highly debatable. Shot placement is the most important factor.
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.
