The Hornady Critical Duty 9mm Luger +P 135gr FlexLock (brand part no. 90226) is built around a high-antimony lead core that’s extremely tough and delivers controlled expansion at a more economical price than similar bonded bullets. Hornady combines two revolutionary features in the FlexLock bullet: the no-clog, patented Flex Tip design and a heavy-duty jacket-to-core InterLock band that mechanically keeps the bullet and core from separating. Nickel plating resists corrosion and makes low-light chamber checks easier, while a cannelured bullet crimped into the case resists setback during repeated feeding. In handgun ammunition for duty and defensive carry, this is Hornady’s Critical Duty loading.

Key Specifications

• The lead core is high-antimony, extremely tough and more economical than a bonded-bullet design.

Frequently Asked Questions

What does the InterLock band do? It’s a mechanical jacket-to-core connection that keeps the bullet from separating on impact, maximizing weight retention and terminal performance.

Why does bullet setback resistance matter? Repeatedly loading and unloading a defensive pistol can push the bullet back into the case over time; the cannelured, crimped design resists that setback, keeping the round safe to carry and re-carry.

How many rounds come in a box? Each box holds 25 rounds of 9mm Luger +P, with 10 boxes to a case.
