Hornady
Hornady Critical Duty 40 S&W ammunition combines barrier-blind reliability with controlled expansion—built for shooters who demand predictable, on-target performance in real-world scenarios. This 175-grain FlexLock load delivers 1010 fps muzzle velocity and 396 ft-lbs of energy, engineered to perform consistently whether your shot encounters glass, steel, or urban obstacles. Law enforcement, armed professionals, and serious defensive shooters trust Critical Duty because it's designed to work when duty demands it.
The FlexLock bullet is Hornady's answer to barrier blindness. Its Flex Tip design won't clog when passing through common obstacles—windshield glass, heavy clothing, drywall, or auto metal—yet still initiates reliable expansion when it reaches soft tissue. This matters in a defensive encounter where you can't predict what's between you and your target.
The InterLoc band is mechanical engineering at work: it locks the jacket to the core so they stay together through barriers and expansion, preserving weight retention and terminal performance across the full range of FBI test protocols. That controlled weight retention means more energy transferred where it counts and less bullet fragmentation that unpredictably degrades performance.
Twenty rounds per box makes this suitable for range training, qualification, or defensive carry rotation. If you're running a 40 S&W for duty, sport, or personal protection and you want ammunition built to deliver under pressure, Critical Duty is worth the investment.

Critical Duty ammunition is purpose-built for defensive and duty use. The FlexLock bullet won't clog when passing through barriers like glass or auto metal, and the InterLoc band keeps the jacket and core together for consistent expansion and weight retention. It's engineered and tested to perform reliably across FBI test barriers—something standard target or practice rounds aren't designed for.
Yes. The Flex Tip design prevents clogging when the bullet encounters barriers like windshield glass, heavy clothing, and steel. This barrier-blind design ensures the round performs predictably regardless of what lies between you and your target—a critical requirement for duty ammunition.
Each box contains 20 rounds of Hornady Critical Duty 40 S&W ammunition.
The InterLoc band is a mechanical lock between the bullet jacket and core. It prevents separation during barrier penetration and expansion, which means the bullet retains more of its weight and delivers more reliable terminal performance. Weight retention translates to better energy transfer and more predictable stopping potential.
