Designed by John Browning, a true genius of firearm design, the .45 ACP (Automatic Colt Pistol) is a handgun cartridge used in the seminal Colt Government Pistol, also known as the 1911. The .45 ACP combines relative accuracy with increased stopping power against human targets. With little muzzle blast and flash, it generates manageable recoil in handguns, operating at a relatively low maximum chamber pressure rating: 21,000 psi. (Compare this to 35,000 psi for the 9mm Parabellum—used by the Luger line of weapons; 37,500 psi for the 10mm Auto—for the Bren Ten pistol; and 40,000 psi for the .357 SIG—used by the SIG Sauer line of weapons). The standard-issue military .45 ACP round uses a two-hundred-and-thirty-grain bullet that travels at a speed of approximately eight hundred and thirty feet per second when fired from the 1911. The low psi related to the ACP reduces bolt thrust, extending the service life of the weapons in which it is used. The full metal jacket (FMJ) version of the .45 ACP increases the mass of the ACP round increasing its effectiveness against human targets because the round is able to easily penetrate tissue, reaching into the central nervous system. The round’s diameter (11.5mm) also generates a substantial permanent wound channel when compared to the standard ACP, which will quickly lower a target’s blood pressure depending on whether any critical organs are touched by the round. The expanding hollow point form of the ACP round is also effective against human targets. A one-hundred-and-eighty-five-grain that travels at 1,050 feet per second will create a significantly large permanent wound cavity in the chest of a full-size target. Though the expanding hollow point achieves decreased penetration when compared to the FMJ round (thus decreasing the chance of striking a vital organ), the large-diameter wounds caused by the expanding hollow point are likely to cause greater blood loss.

The 1911, for which the .45 ACP was developed, is the best-known handgun to use short-recoil principles in its basic design. Short-recoil is derived from what is generally called recoil operation. Recoil operation uses the energy generated by the recoil of a weapon’s discharge to facilitate the extraction and ejection of a spent ACP casing, as well as the chambering of a further round. In short-recoil operation, the barrel and the bolt of the weapon are both set into motion by the weapon’s recoil, moving backward together a short distance, before separating, at which point the barrel is stopped and held in place, while the bolt continues rearward, compressing a recoil spring, which propels the bolt forward again, completing the extraction and feeding process.

At Sarco Inc., we have the 1911 45 parts you need to build your own Government sidearm, or maintain your weapon. From extractors to ejectors, from sears to barrels to recoil springs, Sarco stocks every piece of the 1911. We even have kits, which include every piece needed to build your own 1911 from scratch. There are no fasteners of any type in the 1911 design, except the grip screws, as the main components of 1911 are held in place by the recoil spring. The pistol can be stripped by retracting the slide, removing the slide stop, and removing the barrel.
