Intended Use: The .357 SIG is engineered for high-stakes applications, making it a top choice for law enforcement agencies and civilians alike for self-defense. Its ballistic performance closely mimics that of the .357 Magnum revolver round, providing superior penetration and stopping power, but in a format that is compatible with the higher capacity of semi-automatic pistols.

Caliber/Size: Developed in the early 1990s by SIG Sauer and Federal Cartridge, the .357 SIG is designed to replicate the .357 Magnum’s ballistics in a smaller, semi-automatic cartridge. It is based on a .40 S&W case necked down to accept a 9mm diameter bullet, offering a unique combination of velocity, accuracy, and stopping power.

Performance Characteristics: The .357 SIG is known for its flat trajectory, high velocity, and exceptional stopping power. It is capable of defeating automotive glass and other barriers without significant deflection, making it highly reliable in tactical and self-defense situations. The round’s performance is enhanced by a variety of bullet types, including jacketed hollow points (JHP) for self-defense, ensuring effectiveness against threats.

Material and Construction: Ammunition in the .357 SIG category is produced with high-quality materials, featuring robust brass casings and precisely engineered projectiles. The selection includes various bullet designs to meet different operational requirements, from training and target shooting to tactical and defense scenarios.

Brands and Manufacturers: This category includes products from industry leaders like SIG Sauer—the caliber’s co-developer—alongside other reputable manufacturers such as Sig Sauer, Federal, and Precision One. These brands are synonymous with quality and reliability, offering shooters the best in .357 SIG ammunition.

A Brief History: The .357 SIG cartridge was introduced in 1994 as a collaborative effort between SIG Sauer and Federal Cartridge.
