Hornady Critical Duty Ammunition 9mm Luger +P 135 Grain Box of 25

Clear Product Overview

Hornady Critical Duty 9mm Luger +P 135 Grain FlexLock is an elite law enforcement and tactical self-defense load designed specifically to satisfy strict FBI tactical ballistic testing protocols. Manufactured in the USA by Hornady, this overpressure (+P) load features the heavy-duty FlexLock projectile, engineered to penetrate urban barriers like auto glass, sheet metal, plywood, and heavy clothing without bullet deformation, jacket-core separation, or trajectory deflection.

First, Hornady Critical Duty features a high-density 135-grain FlexLock bullet equipped with a red polymer Flex Tip insert and a heavy-duty InterLock band. Consequently, tactical operators and home defenders achieve consistent barrier-blind terminal expansion and deep target penetration through tough intermediate barriers. In addition, its low-flash propellants prevent flash blindness during low-light defense engagements while preserving firearm chamber cleanliness. As a result, it is the premier defense choice for full-sized service handguns and modern duty sidearms such as the Glock 17/19, SIG Sauer P320, Smith & Wesson M&P 2.0, and Beretta 92FS. Furthermore, its nickel-plated brass cases resist corrosion caused by moisture and environment while gliding smoothly across magazine feed ramps. Therefore, it delivers maximum kinetic energy transfer, flawless semi-automatic action cycling, and match-grade terminal precision.

Real-World Use Information

Tactical shooters and home defenders select Hornady Critical Duty 9mm 135gr +P because it passes every phase of the rigorous FBI Protocol test. Consequently, law enforcement officers and civilian marksmen gain reliable stopping power even when obstacles like drywall, heavy winter coats, or vehicular glass stand between them and the target.

Additionally, the heavy 135-grain bullet weight combined with +P overpressure powder charging maximizes momentum and penetration depth. Therefore, shooters operating full-size duty handguns experience linear penetration trajectories, minimal bullet fragmentation, and immediate energy transfer upon fluid entry.

Compatibility & Requirements

• Firearm Compatibility: Chambered for all modern standard 9mm Luger / 9x19mm handguns and pistol-caliber carbines (PCCs) explicitly rated by their manufacturer for +P overpressure ammunition; optimized for full-size service pistols.

• Usage Restrictions: Tailored specifically for law enforcement duty, home protection, and tactical self-defense; not intended for target plinking or steel-plate training.

• Storage: Store ammunition in a cool, dry area inside its original 25-round box or sealed ammo storage canister for maximum storage shelf life.

Pros & Limitations

Pros:

• FBI-Protocol Barrier-Blind Performance: FlexLock bullet design penetrates auto glass, sheet metal, and wood without jacket separation.

• Patented Flex Tip Technology: Polymer tip prevents cavity plugging through heavy clothing to guarantee terminal expansion.

• InterLock Mechanical Jacket Lock: Fuses jacket to lead core for deep weight-retaining penetration.

• Low-Flash Propellant: Preserves night vision alignment during low-light defense encounters.

Limitations:

• Requires +P Approval: Firearm must be factory-approved for +P overpressure ammunition.

• Optimized for Full-Size Handguns: Designed primarily for full-length service barrels rather than micro-compact concealed carry guns.
