.357 SIG vs 5.7x28mm
The .357 SIG vs 5.7x28mm comparison examines two high-velocity handgun cartridges with different design philosophies. The .357 SIG (125gr JHP at 1350 fps) delivers 388 ft-lbs at 50 yards versus the 5.7x28mm's (40gr JHP at 1800 fps) 203 ft-lbs. Penetration differs notably: the .357 SIG stays within the FBI's optimal zone at 14.4-14.8 inches, while the 5.7x28mm exceeds it at 18.0-18.8 inches. Recoil favors the 5.7x28mm at 1.65 ft-lbs compared to the .357 SIG's 7.14 ft-lbs. The .357 SIG sees use by some law enforcement agencies seeking .357 Magnum performance in a semi-auto; the 5.7x28mm trades bullet weight for velocity and capacity.

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
