5.7x28mm vs 9mm Luger
The 5.7x28mm vs 9mm Luger comparison contrasts a PDW-derived cartridge with the world's most popular pistol round. The 9mm Luger (124gr JHP at 1201 fps) produces 337 ft-lbs at 50 yards while the 5.7x28mm (40gr JHP at 1800 fps) delivers 203 ft-lbs. Penetration differs in opposite ways from ideal: the 5.7x28mm exceeds the FBI's 12-18 inch standard at 18.0-18.8 inches, while the 9mm lands squarely in the optimal zone at 14.7-15.0 inches. The 5.7x28mm recoils less at 1.65 ft-lbs versus the 9mm's 3.84 ft-lbs. The 9mm offers cheaper ammunition, wider pistol selection, and proven terminal performance; the 5.7x28mm provides higher capacity and a flatter trajectory.

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
