Hornady Critical Duty 357 SIG Ammunition 135 Grain Nickel Plated Brass 20 Rounds FlexLock 91296

Hornady’s Critical Duty 357 SIG ammunition is engineered for the demands of real-world defensive scenarios, delivering the toughness, consistency, and terminal performance trusted by professionals. Built around Hornady’s proven FlexLock bullet, this round combines a high-antimony lead core with a heavy-duty jacket-to-core InterLock band, ensuring the bullet stays intact even through common urban barriers. The result is controlled expansion, exceptional weight retention, and dependable penetration when it matters most.

The Flex Tip nose is designed to resist clogging, guaranteeing reliable expansion regardless of clothing or material, while the mechanically locked jacket prevents core separation under high stress. Nickel-plated brass casings add another level of performance, resisting corrosion and making low-light chamber checks fast and intuitive. The cannelured bullet and crimped case work together to eliminate bullet setback during feeding, giving you smooth, consistent operation in high-pressure moments.

Loaded to a muzzle velocity of 1225 fps and producing 450 ft-lbs of energy, this 135-grain 357 SIG round strikes the balance between power, control, and predictable performance. Each cartridge is built with premium components and backed by Hornady’s commitment to quality, making it a trusted choice for home defense or duty use. Packaged in a 20-round box, Critical Duty ammunition delivers the kind of rugged reliability shooters depend on when there’s no margin for error.
