Federal P9HST1S Premium 9mm Luger 124gr HST JHP Ammo 20rd Box

The Federal P9HST1S Premium Personal Defense ammunition delivers consistent expansion and penetration through the proven HST (Hydra-Shok Two) bullet design. This 124-grain jacketed hollow point load represents Federal's latest advancement in personal defense ammunition technology, engineered specifically for reliable performance in critical situations.

What Makes This Different

The HST bullet features a mechanical jacket-to-core bond that virtually eliminates core-jacket separation, even through heavy clothing and intermediate barriers. Unlike standard hollow points that can clog with fabric, the HST design maintains its expansion characteristics through four layers of denim. Independent ballistic testing shows consistent expansion to nearly twice the original diameter while retaining 99% of bullet weight.

Key Features

• 124-grain HST jacketed hollow point bullet with bonded core construction
• Nickel-plated brass cases resist corrosion and provide smooth feeding
• Low-flash propellant reduces muzzle signature in low-light conditions
• Consistent muzzle velocity of 1,150 fps from 4-inch test barrel
• Optimized for standard pressure 9mm Luger chambers
• FBI protocol tested for barrier penetration and expansion
• Premium boxer-primed cases suitable for reloading

Law enforcement agencies nationwide have adopted HST ammunition as their primary duty load due to its predictable terminal performance. The 124-grain weight provides excellent accuracy in most 9mm pistols while generating manageable recoil for rapid follow-up shots. This load performs consistently in temperatures from -20°F to +140°F, maintaining velocity and expansion characteristics across extreme conditions.
