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 caliber ACP
9x17mm, otherwise known as the .380 ACP.
F.A. 43 bullet is a .45 caliber ACP bullet most likely from the Korean War or World War 2. The F.A. stands for Frankford Arsenal.
Assuming it's 7.65x17 Browing...it's the same as .32 ACP.
A typical .380 ACP (Automatic Colt Pistol) bullet weighs around 90-100 grains. However, bullet weight can vary depending on the specific type of ammunition and manufacturer.

Assuming you mean caliber, the caliber simply refers to the diameter of the bullet the gun is designed to fire. American cartridge sizes are expressed as tenths or hundredths of an inch, and European cartridges sizes are expressed as millimeter. A .40 caliber gun fires a bullet that is .40 of an inch in diameter. A 9 millimeter gun fires a bullet that is 9 millimeters in diamter. There are too many variations to list here, but some common handgun calibers are 9 millimeter, 10 millimeter, .40 SW, .38 special, .44 magnum, .45 ACP, .380 ACP.

No, an A380 bullet is significantly larger and more powerful than a 9mm bullet. The A380 bullet is typically used in aircraft cannons and has much greater stopping power due to its higher velocity and larger size.

The 45 GAP operates at slightly higher pressure than standard (non +p) 45 ACP ammunition and by this means is able to generate similar velocity and energy to the 45 ACP cartridge. The 380 Auto cartridge is not only smaller than 9mm Luger, it is also far lower pressure. The 380 Auto delivers far less velocity and energy and cannot handle as much bullet mass as the 9mm.
