.45 Auto +P (.45 Automatic Colt Pistol (ACP) +P) Handgun Cartridges
These cartridges have the same external dimensions as the standard-pressure cartridges and will chamber and fire in all firearms designed for the standard-pressure loadings. The inner dimensions of the +P cartridge are different from the standard-pressure cartridge dimensions and thus allows for higher pressures to be safely achieved in the +P cartridge. If +P loadings are used in firearms not specifically designed for them they may cause damage to the weapon and injuries to the operator.

**See below for further reference regarding the power rankings listed in the tables above:
MV-Muzzle Velocity
Muzzle velocity when fired from a typical handgun. Measured in feet-per-second.
ME-Muzzle Energy
Muzzle energy when fired from a typical handgun. Measured in foot-pounds.
PF-Power Factor
In shooting competition the Power Factor is used to determine the competitive division in which a particular handgun/cartridge can be used. A simple calculation of the bullet's mass times its muzzle velocity.
PF = bull. mass x muzzle vel.
TKO-Taylor Knock Out Formula
Developed by big-game hunter John Howard Taylor in the 1940's. Calculates the relative effectiveness of bullets for hunting game.
TKO = (bull. mass x muzzle vel. x bull. dia.)/7000
