The Hornady Critical Duty Pistol Ammo 9mm Luger +P 135 gr FlexLock brings law enforcement-grade performance to duty and home-defense shooters who need reliable barrier-stopping capability and consistent terminal results, and the Critical Duty series is widely respected for that urban barrier performance reputation. The FlexLock bullet with its FlexTip design minimizes clogging in hollow points, helping function through heavy clothing, auto glass and other barriers while maintaining a controlled expansion and deep penetration that produces the 1110 fps muzzle velocity and 369 ftlbs of muzzle energy expected from a +P 135-grain loading. Shooters will appreciate the corrosion-resistant nickel-plated brass casings for reliable feeding and extraction in semi-autos, and the cartridges designation as HazAir/ORMD and origin in the United States gives procurement clarity for agencies and serious private carriers. Whether you run duty holster drills, train under realistic barrier scenarios, or select a dedicated home-defense load, this Hornady FlexLock offering balances recoil, follow-up shotability and terminal effectiveness in a compact 9mm package thats trusted by security professionals and defensive-minded sportsmen.
