  • The .357 SIG is a pistol cartridge that was developed in 1994 by SIG Sauer and Federal Cartridge. It is based on a necked-down .40 S&W case and is designed to provide higher velocities and better performance than other common handgun cartridges.

    The .357 SIG is known for its high muzzle velocity and flat trajectory, making it popular among law enforcement agencies and self-defense enthusiasts. It is commonly used in semi-automatic pistols such as the SIG Sauer P229 and P226, as well as other firearms that can be chambered for this cartridge.

    Despite its popularity, the .357 SIG is not as widely used as some other handgun cartridges such as the 9mm or .45 ACP. It can be more expensive and may be more difficult to find ammunition and firearms chambered for this cartridge. Nonetheless, it has a dedicated following and is considered a high-performance cartridge that offers excellent accuracy and stopping power.

    When aggregating the ballistic performance of 112 suitable bullets for this caliber, you get an average powder charge of 6.9gr | 0.45g , an average muzzle velocity (V0) of 1371fps | 418m/s , and an average muzzle energy (E0) of 669 Joule.
