Federal Premium Personal Defense .40 S&W 165 gr Hydra-Shok JHP ammo is purpose-built for serious handgun users who need a round they can trust when it matters most. The Hydra-Shok jacketed hollow point has been the standard for law enforcement and defensive shooters for good reason: it combines controlled expansion with deep penetration and near-total weight retention, giving you the stopping power and reliability that come from decades of field-proven design and rigorous testing.

The 165-grain load in .40 S&W delivers the ballistic performance that satisfies even the FBI's demanding penetration protocols. On impact, the Hydra-Shok's notched jacket ruptures along engineered fault lines, allowing the bullet to mushroom in a controlled manner. The hardened center post acts as an internal stop, preventing over-expansion and ensuring the bullet retains nearly all its weight as it passes through the target—a critical factor in barrier-blind performance and energy transfer.

If you're carrying a .40 S&W for personal defense or duty use, Federal Premium Personal Defense rounds give you ammunition engineered by the same maker trusted by law enforcement agencies across the country. Each box contains 20 rounds ready to go. This is ammunition built on the principle that if you hit what you're aiming at, the bullet will do exactly what it's designed to do.
