Hornady Critical Duty 357 Sig Ammunition 135 Grain FTX Polymer Tip Box of 20

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.

• FLEXLOCK® BULLET:  Incorporates two revolutionary Hornady® features: the no-clog, patented Flex Tip® design and the heavy duty jacket-to-core InterLock® band.
• INTERLOCK® BAND:  Works to keep the bullet and core from separating for maximum weight retention and proven terminal performance through all FBI test barriers.
• CORE:  Made of high-antimony lead making it extremely tough, delivering controlled expansion for unparalleled terminal performance consistency through all FBI test barriers. It's also more economical than similar bonded bullets.
• NICKEL-PLATED CRIMPED CASES:  Nickel plating resists corrosion and greatly enhances low-light chamber checks. The cannelured bullet with crimped case ensures no bullet setback during feeding.
