Made in the USA with premium components, Critical Duty ammunition ensures you unlock the full potential of your full sized handgun.

Hornady Critical Defense Cartridge Cutaway


The patented Hornady Flex Tip® design eliminates clogging and aids bullet expansion. A large mechanical jacket-to-core InterLock® band works to keep the bullet and core from separating for maximum weight retention, excellent expansion, consistent penetration and terminal performance through all FBI test barriers.


Bright nickel-plated cases simplify chamber checks in reduced light. Additionally, all Critical Duty® ammunition is loaded with low flash propellant to help preserve night vision in low-light firing.


The core of the bullet is made of high-antimony lead making it extremely tough, delivering controlled expansion for unparalleled terminal performance, and is more economical than similar bonded bullets. The cannelured bullet with crimped case ensures no bullet setback during feeding.
