Automatic Colt Pistol The Model 1911 pistol was developed for the Army. Most bullets (cartridges) had a large base for use in the cylinder of a revolver. The Colt pistol was automatic and used a clip so the cartridge did not have a base that was wider than the bullet. This bullet was specially designed for this gun. It became known as the .45 ACP so it would not be confused with other bullets.
45 ACP
It could be any pistol chambered for one of the several handgun calibers in the .45 family. The most famous .45 handguns are actually chambered for different rounds. The Colt model 1873 "Peacemaker" was offered in .45 Colt or "Long Colt" caliber, among other calibers. And the famous Colt model 1911 was sold in a caliber called .45 ACP (automatic Colt pistol). The .45 ACP is not interchangeable with the .45 Long Colt, but they both fire big heavy bullets at similar velocities.
The Hi-Point Model JHP .45 ACP magazine typically holds 9 rounds of ammunition.

ACP stands for Automatic Colt Pistol. It is used to differentiate two bullets of the same caliber when one is for a pistol and one is for a revolver. For instance, .45 Colt is for a revolver, and .45 ACP is for a pistol. Other than the .45 inch measurement, the two have nothing in common and are not interchangeable; the .45 ACP cannot be used in a revolver chambered for .45 Colt and vice versa. The cartridge length and capacity are just two of the factors that make each different from the other.
Depends on make and model of the firearm. In general, most .25 ACP pistols have a six or seven round magazine.

It's important to check the specific derringer model, as some may be chambered for only one type. Always refer to the manufacturer's specifications for accurate information.
