The Hornady Critical Duty Handgun Ammo 45ACP +P 220gr FlexLock delivers a law-enforcement-grade option from Hornadys Critical Duty series that combines controlled expansion and barrier-stopping capability for demanding defensive scenarios. Featuring the FlexLock bullet with its polymer Flex Tip, this +P 220-grain round maintains reliable feeding while minimizing the clogging that hampered earlier hollow-point designs, which is why agencies and security professionals favor it for urban barrier performance and patrol duty. With a muzzle velocity around 975 fps and muzzle energy near 464 ft lbs, the heavy 220-grain projectile provides momentum for deep, consistent penetration through common barriers encountered in real-world incidents, and the nickel-plated brass casing offers corrosion resistance and smooth chambering for high-cycle use. Whether selected for home defense, duty carry, or training with defensive loads in service pistols chambered for .45 ACP, Critical Duty FlexLock balances terminal performance and dependable function shot after shot. If youre researching Hornady 45 ACP +P ammunition for barrier tests, duty logs, or defensive loadouts, this rounds reputation for controlled expansion and reliable feeding makes it a standout choice.
