A: Automatic Colt Pistol is correct. This term has been used for over 100 years with a lot of history behind it. Today, this does not mean the ammunition must be used in a pistol from Colt. Other ACP calibers may even be used in rifles or carbines. ACP will commonly indicate the ammunition will be used in a semi auto pistol, rather than a revolver. This is important when considering some calibers such as the 32. There is a round designed for both pistols (autos and revolvers) and should not be interchanged.
This 380 Auto ammo could also be named 380ACP. Some manufacturers label their ammo with different lettering, but they mean the same thing.
