CustomLite“Barrier Blind” performance from a 45 Auto!

Meeting the FBI protocol handgun ammunition terminal performance test requirements is no small task – especially with a bullet as large as .45 caliber – but Hornady engineers have succeeded! Featuring the 220 grain FlexLock® bullet, the Critical Duty 45 Auto+P delivers industry leading performance through all FBI established urban barriers.


The FlexLock® bullet features the Hornady exclusive Flex Tip® technology that prevents bullet clogging while enhancing barrier penetration and terminal performance.

Additionally, all Critical Duty® loads feature low-flash propellants and nickel plated cartridge cases with sealed primers and case mouths.
