.357 SIG vs 9mm Luger
The .357 SIG vs 9mm Luger comparison pits a high-velocity bottleneck cartridge against the world's most popular defensive handgun round. The .357 SIG (125gr JHP at 1350 fps) delivers 388 ft-lbs at 50 yards while the 9mm Luger (124gr JHP at 1201 fps) produces 337 ft-lbs at the same distance. Both calibers achieve optimal FBI penetration depths, with the 9mm reaching 14.7-15.0 inches and the .357 SIG hitting 14.4-14.8 inches. The 9mm generates significantly less recoil at 3.84 ft-lbs compared to the .357 SIG's 7.14 ft-lbs, making follow-up shots faster and easier. Performance varies with ammunition selection and firearm platform.

Comparison of estimated penetration depth in 10% ballistic gel between .357 SIG and 9mm Luger at self-defense distances.
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
