History of 45 ACP Ammo

The .45 ACP, developed by John Moses Browning in 1905, is a cornerstone of American ammunition known for its power and reliability. It offers excellent stopping power and accuracy, making it ideal for personal protection, law enforcement, and competitive shooting. Originally designed to meet the U.S. Cavalry's need for a more effective round, it became the official sidearm of the U.S. Armed Forces in 1911 with the M1911 pistol. Favored by units like the FBI's Hostage Rescue Team and LAPD SWAT, the .45 ACP's versatility and effectiveness continue to make it a trusted choice over a century later.

  • 4 Inch Grouping at 100 yds said:

    This ammo is smoking hot. Really fast. My groupings were better than with standard 230 gr. ammo. Gets the job done.

    Tryed the penetration test...the rounds mushroomed perfectly! They are very accurate also! These are going to be used for self defense!
