The .45 Colt is a centerfire handgun cartridge, designed around the balance of controllable recoil, reliable feeding, and terminal performance that defensive and target shooters look for. A representative 250-grain loading leaves the muzzle at roughly 860 fps and carries about 411 ft-lbs of energy, with a G1 ballistic coefficient near 0.138. With a modest BC, it sheds velocity faster downrange and is best kept to shorter distances. In practice it is used most for self-defense, concealed carry, and target/competition shooting at handgun distances, where shot placement matters far more than raw power. Recoil is generally manageable for the class, and our database tracks 1 factory loading so you can compare bullet weights and velocities for your specific use.
