.357 SIG

Caliber Overview
The .357 SIG is a high-performance pistol cartridge renowned for its exceptional velocity and stopping power, making it a favorite among law enforcement and self-defense enthusiasts. Developed in the early 1990s by SIG Sauer in collaboration with Federal Cartridge Company, this caliber was designed to mimic the ballistic performance of the .357 Magnum in a semi-automatic pistol platform. It offers superior penetration and expansion compared to standard 9mm rounds, positioning it as a go-to choice for personal protection and professional tactical use. At AmmoSouth, we stock a wide range of .357 SIG ammunition to meet the needs of discerning shooters seeking reliability and precision.
Key Specifications
The .357 SIG features a bullet diameter of 0.355 inches (9mm), with typical grain weights ranging from 115 to 150 grains for optimal balance of speed and energy. This cartridge generates high muzzle velocities, often exceeding 1,300 feet per second, which results in moderate to high recoil that experienced shooters can manage effectively. Ballistically, it delivers excellent energy transfer and flat trajectories, ideal for accurate shooting at distances up to 50 yards. Compatible firearms include popular models like the SIG Sauer P226, P229, and modified Glocks such as the Glock 31 or 32. At AmmoSouth, our selection ensures compatibility with these platforms, backed by detailed product specifications for informed purchasing.
Applications
Primarily utilized for self-defense, the .357 SIG excels in scenarios requiring reliable penetration through barriers, such as in urban environments or law enforcement operations. Its high velocity makes it suitable for tactical applications, including duty carry and home defense, where quick expansion and stopping power are critical. Enthusiasts also employ it in competitive shooting, particularly in action pistol events, due to its accuracy and manageable recoil. For hunting small game, this caliber provides effective terminal performance, though it’s less common in that role compared to rifle cartridges. AmmoSouth offers .357 SIG rounds tailored for these diverse applications, ensuring shooters have access to premium options.
Ammunition Types
.357 SIG ammunition is available in various bullet types to suit specific needs. Full Metal Jacket (FMJ) rounds are ideal for target practice and training, offering reliable feeding and affordability for range sessions. Jacketed Hollow Point (JHP) bullets are designed for self-defense, expanding upon impact to create larger wound cavities and maximize stopping power. Other options include specialized loads like bonded or barrier-penetrating variants for law enforcement, which maintain integrity through tough materials. Popular brands such as Federal, Winchester, and SIG Sauer provide these types, each optimized for velocity and accuracy. At AmmoSouth, we curate a selection of these high-quality options to enhance your shooting experience.
Key Benefits
One of the key advantages of .357 SIG is its superior ballistic performance, boasting higher velocities and better penetration than comparable calibers like the 9mm or .40 S&W, making it highly effective for self-defense without excessive recoil. Its accuracy at extended ranges and versatility across applications provide shooters with a reliable edge in both civilian and professional settings.
