Bullets: .45 ACP (11.43x23mm)

The .45 ACP (automatic colt pistol) also known as .45 auto, was a bullet designed by John Browning in 1904, to be used in a colt prototype pistol but was later used in Colt 1911 which was adopted by US army.

Performance:

The .45 ACP combines high accuracy with stopping power and the ability to do massive internal damage compared to smaller bullets. This makes it a deadly bullet to be used against human targets, it also operates on lower chamber pressure compared to 9mm parabellum (240 MPa) and .40 S&W (260 MPa), the .45 operates with only (145 MPa) this elongates the life time of service for the gun .45 is used in.

How ever just like most of the large size bullets its a low velocity round and because of its large size it has low penetration against armour, but with out Armour its large size becomes its advantage even without hollow point (HP) or soft points (SP) this bullet's size gives it ability to give a heavy, deep and permanent damage making a wide wound, and heavy hydro-static shock wave.

Its moderate recoil allows the user to sustain his accuracy and rate of fire when shooting multiple rounds at a target.

The bullet energies varies form 470 J to 680 J depending on the manufacturer, also this bullet is available in variety of types from hollow points (HP), soft points (SP) to full metal jacket (FMJ).
