The .357 SIG was designed to replicate .357 Magnum ballistics in a semi-automatic pistol. Using a necked-down .40 S&W case, it launches a 9mm bullet at velocities exceeding 1,400 fps. The .357 SIG is known for its excellent barrier penetration and is used by several federal agencies.
Primary uses: law enforcement, self-defense, duty carry.
When shopping for .357 SIG firearms and ammunition, consider factors such as barrel length, bullet weight, velocity, and intended application.
