Depends on which powder, and which loading of the 9mm.
.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.
The first gun you get is a 9mm handgun in the second chapter. On the rooftop, go to the first turnoff. A video will happen and a man will threaten you, then get killed by a zombie. Grab the gun he dropped.
A 9mm of some type. What markings are on 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.
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.
