Hornady Critical Duty 45 ACP +P 220 Grain FlexLock Ammo - 20 Rounds

The Hornady Critical Duty 45 ACP +P ammunition in 220 grain FlexLock is purpose-built for serious defensive carry and duty use. This is the round trusted by law enforcement professionals and civilians who demand reliable, consistent performance when it matters most. Loaded to +P pressure, it delivers 975 fps muzzle velocity and 464 ft-lbs of energy from a standard 45 ACP platform—real stopping power without requiring exotic guns or loads.

The FlexLock bullet is where Hornady's engineering shines. It combines a flex tip that initiates expansion reliably through common barriers (heavy clothing, drywall, glass) without plugging or deforming, paired with an InterLock band that mechanically locks the jacket to the core. This design means controlled, consistent expansion and maximum weight retention—the bullet stays together and does its job. The core uses high-antimony lead alloy for toughness and predictable terminal performance. Hornady's testing proves this round passes every FBI barrier protocol, round after round, with no surprises.

The nickel-plated brass case resists corrosion, so your carry ammo stays reliable whether you rotate stock regularly or keep the same box in your nightstand for months. Each box contains 20 rounds—enough for defensive practice, qualification, and carry duty without overbuying. If you run a 45 ACP for home defense, duty, or serious personal protection, this ammunition represents the kind of thoughtful design and real-world testing that separates carry ammo from range fodder.

Frequently Asked Questions

Is Critical Duty 45 ACP +P safe to shoot in my standard 45 ACP pistol?

How does the FlexLock bullet perform through barriers?

Hornady designed FlexLock to expand reliably even after passing through common defensive barriers—heavy clothing, drywall, vehicle glass, and other intermediate materials.
