The Hornady Critical Duty Handgun Ammo 9mm +P 124 gr FlexLock delivers the kind of barrier-blind stopping power home defenders and tactical shooters ask for, built as part of Hornadys Critical Duty series to meet demanding FBI Protocol performance through urban obstructions; its FlexLock bullet combines the patented Flex Tip and a mechanical jacket-to-core InterLock band to prevent clogging, promote reliable expansion, and retain weight when passing through common barriers, translating to consistent penetration and terminal performance from a full-size handgun. With +P pressure, a 124-grain load, nickel-plated brass casing, and an advertised 1,175 fps muzzle velocity producing roughly 380 ftlbs of energy, this round offers elevated velocity and energy for duty-style engagements and personal protection scenarios where over-penetration control and barrier mitigation matter. Shooters will appreciate reliable feeding in service pistols and the corrosion-resistant appearance of the nickel-plated brass, while range instructors, range officers, and armed professionals will find the Critical Duty line aligns with defensive training and real-world contingencies. Made in the United States and labeled for safe transport, this Hornady FlexLock load is aimed at those who carry or deploy full-size handguns for defensive and duty applications.
