Hornady Critical Duty® Ammo 40 S&W 175 gr Flexlock® Duty 20/Box

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.
