Hornady’s Critical Duty load is designed to meet the needs of those who demand superior barrier penetration and prefer a full-size handgun for their personal protection. 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 FlexLock bullet incorporates two revolutionary Hornady features to deliver superior barrier penetration and consistent performance. A large mechanical jacket-to-core InterLock band works to keep the bullet and core from separating for maximum weight retention, while the Flex Tip eliminates clogging and aids bullet expansion. The core is made of high-antimony lead making it extremely tough, delivering controlled expansion for unparalleled terminal performance consistency and is more economical than similar bonded bullets.
