Designed to meet the needs of those who demand superior barrier penetration and prefer a full‑size handgun for their personal protection. Critical Duty is loaded with the tough Hornady FlexLock bullet that delivers "barrier blind" performance when shot through common urban barriers. The FlexLock bullet incorporates two revolutionary Hornady features to deliver superior barrier penetration and consistent performance in FBI tactical handgun ammunition tests (FBI Protocol). 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.
