10mm Auto vs .357 SIG
Part of our full caliber comparison chart — energy, drop and recoil for every handgun caliber side by side.
The 10mm Auto vs .357 SIG comparison pits two high-performance semi-automatic cartridges against each other. The 10mm Auto (175gr JHP at 1150 fps) uses a heavier bullet for 429 ft-lbs at 50 yards, while the .357 SIG (125gr JHP at 1350 fps) trades mass for velocity to produce 388 ft-lbs. Both achieve optimal FBI penetration depths: the 10mm reaches 15.5-15.9 inches and the .357 SIG hits 14.4-14.8 inches. Recoil runs similar with the 10mm at 7.69 ft-lbs and .357 SIG at 7.14 ft-lbs. The 10mm offers more versatility with load options from mild to full-power. Performance varies with ammunition selection and firearm platform.

10mm Auto vs .357 SIG Bullet Penetration
Comparison of estimated penetration depth in 10% ballistic gel between 10mm Auto and .357 SIG at self-defense distances.
Self-Defense Ammunition Penetration
Notes:
- FBI standard for optimal penetration is 12-18 inches in 10% ballistics gel
- These penetration figures come from a model of sectional density, velocity and expansion, not from gel tests. Use them to compare the two calibers, not as a measured result.
- Actual results may vary depending on clothing barriers and other factors
10mm Auto vs .357 SIG Recoil
Comparing recoil energy and impulse between 10mm Auto and .357 SIG.
10mm Auto Recoil (Self-Defense Load)
.357 SIG Recoil (Self-Defense Load)
Notes:
- Recoil calculations based on bullet weight, velocity, powder charge, and firearm weight
- Recoil energy indicates the felt force when firing the weapon
- Recoil impulse represents momentum transfer during firing
- Actual felt recoil can vary based on grip, stance, and firearm design
