Federal Premium Personal Defense 9mm Luger ammunition in 124 grain HST JHP (hollow point) is purpose-built for self-defense and personal protection. The HST (Hydra-Shok Two) projectile has earned trust with law enforcement agencies worldwide because it delivers the terminal performance that matters when it counts—reliable expansion, controlled penetration, and consistent shot-to-shot reliability. Each box contains 20 rounds loaded to proven specifications.

The HST hollow point design is engineered to expand reliably even after passing through intermediate barriers like clothing, drywall, or vehicle glass—situations that can fail lesser defensive rounds. The bullet's jacket and core stay bonded together through the toughest materials, which means you get near-complete weight retention and the penetration depth needed for effective personal defense without the risk of dangerous overpenetration into unintended targets.

Federal's loaded these rounds with a nickel-plated case for reliable feeding and maximum corrosion resistance, paired with a high-performance primer system that ignites consistently across a wide range of conditions. The Federal 9mm HST also meets the demanding FBI test protocol—the gold standard by which law enforcement evaluates duty ammunition for performance and reliability. If you're carrying for protection, you want ammunition that's been proven in the field and tested under real-world conditions.
