Hornady Critical Duty .45 ACP+P ammunition (part no. 90926) loads a 220-grain FlexLock bullet built for duty and defensive carry, where barriers and heavy clothing cannot be allowed to stop expansion. Hornady builds the bullet around a high-antimony lead core that is tough enough to deliver controlled expansion at a more economical price than a similar bonded bullet. The FlexLock design combines Hornady’s patented no-clog Flex Tip with a heavy-duty mechanical InterLock band that locks the jacket to the core, preventing separation for maximum weight retention through barriers. Nickel plating resists corrosion and makes low-light chamber checks easier, while a cannelured bullet crimped into the case prevents bullet setback during feeding. For duty and personal-defense carry, this is handgun ammunition built to perform after barrier penetration, not just on paper.

Key Specifications

• The chambering is .45 ACP+P, running in +P-rated .45 ACP pistols for elevated velocity.
• The bullet weighs 220 grains, a heavy-for-caliber weight tuned for duty performance.
• The bullet uses a high-antimony lead core, tough enough for controlled expansion at a lower cost than bonded designs.
• The Flex Tip is a no-clog design, so the hollow point still expands after passing through heavy clothing.
• An InterLock band mechanically locks the jacket to the core, maximizing weight retention through barriers.
• Cases are nickel-plated brass, resisting corrosion and improving low-light chamber checks.
• A cannelured, crimped bullet resists setback during repeated feeding from the magazine.
• Each box holds 20 rounds, a practical duty-ammo quantity for carry and qualification.
• Cost runs about $1.60 a round, competitive pricing for a premium duty load.

Frequently Asked Questions

Will this bullet still expand after passing through clothing? Yes, the no-clog Flex Tip is designed specifically to resist clogging so the hollow point expands reliably even after barrier penetration.

What does the InterLock band do? It mechanically locks the jacket to the core, preventing separation so the bullet retains more of its weight for deeper, more consistent penetration.

Why is bullet setback a concern in a defensive pistol? Repeated chambering can push a bullet back into the case, raising pressure; the cannelured, crimped design here resists that setback.
