.40 S&W vs .44 Magnum
The .40 S&W vs .44 Magnum comparison matches a modern service cartridge against the most powerful mainstream revolver round. The .44 Magnum (240gr JHP at 1350 fps) delivers 806 ft-lbs at 50 yards, nearly doubling the .40 S&W's (165gr JHP at 1175 fps) 413 ft-lbs. The .40 S&W achieves optimal FBI penetration at 14.9-15.3 inches while the magnum exceeds requirements at 21.7-22.2 inches. Recoil differs dramatically: the .40 S&W produces 5.94 ft-lbs versus the magnum's punishing 22.01 ft-lbs. The .40 S&W offers semi-auto capacity for defensive use while the .44 Magnum excels for hunting and bear country. Performance varies with ammunition selection and firearm platform.

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
