40 S&W 175 gr. FlexLock® - Item No. 91375
The Federal Bureau of Investigation (FBI) completed an extensive evaluation process and chose Hornady Critical Duty® 40 S&W pistol ammunition as its contracted service ammunition.
The patented Hornady® Flex Tip® design of the FlexLock® bullet 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 and consistent penetration and terminal performance through all FBI test barriers.
The FlexLock® is an “intelligent bullet” that reacts differently depending on the barrier it encounters, delivering “barrier blind” performance after penetrating urban barriers such as plywood, sheet metal and even auto glass.
Bright nickel plated cases eliminate cartridge case tarnish, and the highly visible silver nickel simplifies 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.
For the ultimate in tactical terminal ballistic performance through all FBI established urban barriers, choose Critical DUTY® ammunition.
