Product Overview: 357 Sig Ammunition
The .357 Sig is a high-performance pistol cartridge designed by the Swiss-German company SIG Sauer in 1994. It’s primarily known for its accuracy, flat trajectory, and high muzzle velocity, making it a popular choice among law enforcement and self-defense enthusiasts. The cartridge was developed by necking down a .40 S&W case to accept a 9mm (.355 inch) bullet. This design allows for the .357 Sig to deliver greater energy and improved penetration compared to the 9mm Luger, while maintaining manageable recoil.
