No. The diameter is the same, but the bullets still differ in length and weight.
Noop. A 380 is about 35/100th of an inch (diameter of bullet), or 9mm A 32 is about 32/100th of an inch. This is 8.1mm
NO!! Although the bullet diameter is the same, the case length is different and should not chamber in the 380 caliber handgun.
Yes they is a differnent. When people say "38" they usually mean .38 special, which is a revolver cartridge. .380 ACP is a semi-automatic cartridge. The bullet in a .380 cartridge, even though it's called .380, is actually very slightly smaller in diameter, and lighter than the bullet in a .38 cartridge. The .38 bullet is 0.357 inches in diameter while the .380 is 0.350 inches in diameter. Technically, the .380 cartridge is considered part of the 9 mm class of bullets. [9 mm x 19 mm = 9 mm Luger or 9 mm Parabellum, 9 mm x 18 mm = 9 mm Tokarov, and 9 mm x 17 mm = .380 ACP]
