Overview 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.

    This round will stop anyone in his tracks. If after seeing the Hi-Point 45 ACP handgun they choose to advance on me, they won't get very far.

    A pleasant surprise for quality in value provided and accuracy. Performed well in 3 different firearms ( 2 pistols, 1 carbine style rifle) . Had previous excellent experience with various loads of .22 caliber offerings from this manufacturer.

  • Steven said:

    Both good penetration and very good expansion. It allowed me to exercise good control over the weapon.

  • n/a said:

    My favorite jhp ammo! Accuracy and power unmatched!

  • Lou said:

    The bullet design seems like a good concept, the ballistic gel tests that I've seen regarding the Honey Badger design were impressive. The concern: The very first round I tried to feed into my Dan Wesson 1911 jammed solid on the feed ramp. Subsequent tries had the same result and the cartridge suffered ~1mm of bullet setback. That particular cartridge didn't appear any different than the others. I cycled other rounds from the same box several times without issue or bullet setback. Maybe the first round I tried was defective. The next time I go to the range I'll try them out.
