The Hornady Critical Duty 9mm Luger +P 124gr FlexLock (brand part no. 90216) offers the lighter of the two bullet weights in Hornady’s +P Critical Duty lineup, running a touch faster than the 135-grain option for shooters who prefer that balance. Hornady builds this round around the same patented FlexLock technology, a no-clog Flex Tip bullet backed by a mechanical InterLock band that keeps the jacket and core locked together through impact. Nickel-plated cases resist corrosion and stand out for easy low-light chamber checks. In handgun ammunition for duty and defensive carry, this is the lighter, faster FlexLock option.
