Can you fire a 9mm bullet out of 380 bersa?

No, you cannot fire a 9mm bullet out of a .380 Bersa handgun. The .380 ACP (Automatic Colt Pistol) and 9mm Parabellum (9x19mm) cartridges are different in size and specifications. Attempting to fire a 9mm round in a .380 firearm could cause serious damage to the gun and potentially injure the shooter. Always use the correct caliber ammunition specified by the manufacturer.
