The Hornady Critical Duty 9mm Luger 135gr FlexLock (brand part no. 90236) brings the same duty-grade FlexLock technology as Hornady’s +P loading, built at standard pressure for pistols not rated for +P ammunition. Hornady still builds this round around a high-antimony lead core and the patented, no-clog Flex Tip design, backed by a mechanical InterLock band that keeps the jacket and core from separating on impact. Nickel-plated cases resist corrosion, and a cannelured, crimped bullet resists setback through repeated feeding cycles. In handgun ammunition for duty and defensive carry, this is the standard-pressure Critical Duty option.
