Product Description
Hornady Critical Duty in 9mm 135gr FlexLock is the law enforcement and serious civilian carry load engineered to meet and exceed the FBI's entire barrier protocol — bare gelatin, heavy clothing, steel, plywood, wallboard, and auto glass — with consistent expansion and weight retention through every test medium. The FlexLock bullet combines the patented Flex Tip technology with a mechanically locked InterLock band that prevents jacket-core separation during extreme-barrier penetration, where bonding alone can fail. At 1,010 fps from a full-size service pistol, the 135-grain projectile is the heaviest-for-caliber subsonic 9mm duty load in the Hornady lineup, providing maximum sectional density and deep penetration with controlled expansion. Critical Duty is the load Hornady designed for service-sized pistols and duty holsters rather than compact carry guns — if you run a Glock 17, M&P, or CZ P10F for work or home defense, this is the load that was built for your platform. Nickel-plated brass, low-flash propellant, and controlled chamber pressure round out a duty-class spec sheet.
