.40 S&W vs .45 ACP
Comparing .40 S&W vs .45 ACP reveals distinct differences between these popular defensive calibers despite their similar applications. The .40 S&W (165gr JHP at 1175 fps) maintains a significant energy advantage, delivering 413 ft-lbs at 50 yards compared to the .45 ACP's (230gr JHP at 850 fps) 343 ft-lbs. The penetration characteristics favor the .40 S&W, which reaches 14.9-15.3 inches, placing it squarely within FBI optimal standards, while the .45 ACP achieves 12.2-12.3 inches at the lower threshold of recommended penetration. Recoil characteristics are remarkably similar, with the .40 S&W generating 5.94 ft-lbs of recoil energy compared to the .45 ACP's 6.06 ft-lbs. Cost considerations favor the .45 ACP, with ammunition starting around $0.26 per round compared to $0.31 for .40 S&W. Remember that performance varies considerably with different ammunition selections and firearm platforms, so these figures represent typical defensive loadings rather than definitive performance benchmarks.

Self-Defense Ammunition Penetration
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
