NEVER FIRE AMMUNITION IN A WEAPON NOT MARKED, CHAMBERED AND DESIGNED FOR IT. DANGER, DANGER, DANGER, DANGER. Don't do it.
.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. Not all 9mm cartridges are the same. 9x19 (a.k.a., 9mm Luger, 9mm Parabellum), for example, is different, hence, not compatible with other 9mm cartridges, such as the 9x17 (a.k.a., .380 ACP), 9x18 Makarov, 9x21, 9x23 Mauser, etc.
NO. The .380 ACP is a 9 x 17 cartridge. The 9x18, also known as the 9mm Makarov, is not truly a 9mm cartridge- it is 9.27mm. The cartridge is too long, too fat, and too powerful to be shot in a .380 ACP pistol.
Only if it is the same type. There are different types of 9mm and they do not interchange as a rule. For example, the Walther PP fires a .380 ACP round, known as 9mm Kurz. This cartridge is shorter and not as powerful as the 9mm Parabellum, also called 9mm Luger.
Any gun that shoot a 9 millimeter bullet.
No, the bullet will not seat.
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.
Many makers offer firearms that shoot the 380 ACP.
No. The SMG is a pistol caliber machine gun, such as 9mm, .45 ACP, etc. The AK is an automatic rifle. You may see them referred to as an assault rifle.
get a standard 9mm hand gun and shoot your balls.
They are the same, but the word 9mm is shorter. I disagree: when you buy a gun that is 9mm it will be different bullets that you buy- 9mm, ironically, are longer. So yes, a 9mm is stronger. Please specify whether you mean the gun itself, or the round you intend to be firing.
