.44 Magnum vs .45 ACP

Examining the .44 Magnum vs .45 ACP ballistic comparison highlights the dramatic differences between these iconic calibers. The .44 Magnum (240gr JHP at 1350 fps) demonstrates overwhelming energy superiority, maintaining 806 ft-lbs at 50 yards compared to the .45 ACP's (230gr JHP at 850 fps) 343 ft-lbs. This translates to more than double the energy throughout its trajectory. Penetration characteristics differ significantly, with the .44 Magnum reaching 21.7-22.2 inches, well beyond optimal defensive standards, while the .45 ACP achieves 12.2-12.3 inches, falling within ideal self-defense parameters. The recoil differential is substantial, with the .44 Magnum generating nearly four times the recoil energy (22.01 ft-lbs vs 6.06 ft-lbs). Cost significantly favors the .45 ACP, with ammunition starting around $0.26 per round compared to $0.78 for .44 Magnum. Remember that performance varies considerably with different ammunition selections and firearm platforms, so these figures represent typical loadings rather than definitive performance benchmarks.

Notes:

  • FBI standard for optimal penetration is 12-18 inches in 10% ballistics gel
  • Our penetration data is calculated using mathematical models based on sectional density, velocity, and expansion factors. While not actual gel tests, our calculations have been validated against manufacturer test data and provide reliable estimates for comparison purposes.
  • Actual results may vary depending on clothing barriers and other factors
