.45 ACP For Sale


The .45 ACP (Automatic Colt Pistol)also called 45 Auto is a well-known and widely used caliber in the world of firearms. Developed by John Browning in the early 20th century, has stood the test of time and remains a popular choice among law enforcement, military personnel, and civilian shooters. 


The .45 ACP was first introduced in 1904 due to a collaboration between John Browning and Colt’s Manufacturing Company. It was specifically designed for use in the Colt Model 1911 pistol, which the United States Army adopted in 1911. The 45 Auto quickly gained a reputation for its stopping power and reliability, making it a preferred choice for military sidearms.

During World War I and II, the .45 ACP proved its effectiveness on the battlefield. Soldiers praised its ability to hinder enemy combatants with fewer shots than other calibers. This reputation continued to grow, solidifying the 45 Auto as a symbol of American firepower.


The .45 ACP is a large caliber round with a bullet diameter of .451 inches. It typically fires a bullet weighing between 185 and 230 grains. The standard velocity for a .45 ACP round is around 830 feet per second, although variations are available with higher rates.

One of the key advantages of the .45 ACP is its stopping power. Combining a heavy bullet and moderate velocity results in significant energy transfer upon impact. This makes it highly effective for self-defense, as it can incapacitate an attacker quickly and decisively.

This allows for better control and follow-up shots, making it easier for shooters to stay on target. The larger bullet diameter also contributes to a wider wound channel, increasing the chances of hitting vital organs and stopping an assailant.

Over a century of use in various conflicts and law enforcement engagements has demonstrated its effectiveness in real-world scenarios. This reliability and stopping power have earned the45 Auto a reputation as a “man-stopper” round.

Another advantage is the availability of ammunition. The .45 ACP is widely produced by numerous manufacturers, ensuring a steady supply of affordable and reliable cartridges. This accessibility makes it easier for shooters to find ammunition for practice, self-defense, or competition.

The .45 ACP also offers versatility in terms of bullet selection. From hollow points for self-defense to complete metal jacket rounds for target shooting, a wide range of bullet types are available for different applications. This flexibility allows shooters to tailor their ammunition choices to their specific needs.


The .45 ACP finds its place in various applications, including self-defense, law enforcement, and competition shooting. Its stopping power and reliability make it an excellent choice for those seeking a self-defense firearm. The45 Auto’s ability to incapacitate an attacker quickly can provide peace of mind to individuals concerned about personal safety.

In competitive shooting, the .45 ACP has found a home in disciplines such as USPSA (United States Practical Shooting Association) and IDPA (International Defensive Pistol Association). Its power and controllability allow shooters to engage targets accurately and quickly, making it a popular choice among competitors.
