5 Facts About 45 Acp

The 45 ACP, or Automatic Colt Pistol, is a widely used cartridge designed by John Browning in the early 20th century.

In this article, we will delve into the history and characteristics of the 45 ACP, exploring its development, design, and uses.

The 45 ACP was first introduced in 1905, when John Browning was working with Colt's Manufacturing Company to create a new semi-automatic pistol. At the time, the US military was looking for a more effective sidearm, and Browning's design fit the bill. The 45 ACP was designed to be a more powerful alternative to the 38 Long Colt, which was the standard issue sidearm at the time. With its larger caliber and more potent load, the 45 ACP quickly gained popularity among shooters.
