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

At the core of this ammunition is the 135 grain FlexLock® bullet, developed specifically to meet the demanding requirements of FBI tactical handgun ammunition testing protocols. The FlexLock projectile combines two innovative Hornady technologies to provide dependable “barrier blind” performance. The patented Flex Tip® design prevents clogging while helping initiate reliable expansion, allowing the bullet to perform consistently after passing through challenging barriers.

A heavy-duty InterLock® jacket-to-core band works to lock the bullet and core together, helping prevent separation during impact. This design maximizes weight retention, improves penetration, and delivers controlled expansion for reliable terminal performance. The tough, high-antimony lead core is engineered for strength and consistency, providing dependable results across a wide range of defensive scenarios.

Hornady Critical Duty ammunition is built with the needs of law enforcement, security professionals, and serious defensive shooters in mind. The 357 SIG cartridge offers a powerful combination of velocity, accuracy, and manageable recoil, making it a popular choice for those who want high performance from a duty-sized handgun. With a sectional density of .153 and a ballistic coefficient of .170 (G1), this 135 grain load provides stable flight characteristics and predictable performance.

Every round is loaded using premium components, including brass-plated cases that resist corrosion and provide improved visibility for quick chamber checks in low-light conditions. The cannelured bullet and crimped case design help prevent bullet setback during feeding, ensuring reliable operation when it matters most. Low-flash propellant is also used to help reduce muzzle flash and preserve night vision during low-light defensive situations.

Hornady Critical Duty ammunition represents a commitment to precision engineering and dependable performance. Whether carried for duty use, personal defense, or everyday protection, this 357 SIG load provides the confidence that comes from ammunition designed to perform under demanding conditions.

Packaged in a 20-round box, Hornady Critical Duty 357 SIG 135 Grain FlexLock ammunition delivers advanced bullet technology, reliable components, and the barrier-penetrating performance serious shooters expect from Hornady.
