Hornady Critical Duty 40 S&W 175gr FlexLock - 20 Round Box

The Hornady Critical Duty 40 S&W delivers consistent barrier penetration and terminal performance engineered specifically for law enforcement applications. This 175-grain FlexLock ammunition combines proven ballistic technology with premium components to meet FBI protocol standards across all barrier types.

What Makes This Different

The FlexLock bullet design features an elastomer tip that prevents clogging when passing through barriers like heavy clothing, wallboard, and auto glass. Unlike traditional hollow points that can plug and fail to expand, the flexible polymer insert ensures reliable expansion while maintaining penetration depth. Independent testing shows this load consistently achieves 12-18 inches of penetration in ballistic gelatin, meeting FBI specifications for duty ammunition.

Key Features

• 175-grain FlexLock bullet with elastomer tip prevents barrier clogging
• Nickel-plated brass cases resist corrosion and ensure smooth feeding
• Low-flash propellant reduces muzzle signature in low-light conditions
• Cannelured bullet with InterLock ring prevents jacket separation
• Meets FBI Protocol 10% ballistic gelatin standards
• Premium primers provide consistent ignition across temperature ranges
• 20 rounds per box, 10 boxes per case (200 total rounds)

This ammunition performs consistently across environmental conditions, from subzero temperatures to desert heat. The controlled expansion design maintains effectiveness through intermediate barriers while delivering maximum energy transfer to the target. Law enforcement agencies nationwide have adopted Critical Duty loads for their proven reliability in high-stakes situations where ammunition failure is not an option.
