Hornady Critical Duty 45 Auto 220gr FlexLock - Self-Defense Ammo

Hornady Critical Duty 45 Auto 220gr FlexLock is the .45 ACP entry in the Critical Duty line — built for agencies and officers who carry .45 platforms and require ammunition that meets FBI barrier protocol standards for consistent terminal performance through intermediate barriers.

.45 ACP's larger diameter produces a wide wound channel; the FlexLock's barrier-defeating design ensures that wound channel comes from a bullet that expanded, not one that packed with fabric and arrived as an FMJ. At 220 grains, this FlexLock load meets FBI barrier protocol requirements — expansion is consistent through heavy clothing and intermediate barriers at defensive velocities. Nickel-plated brass eases chamber checks in low-light conditions and holds up better than standard brass during extended carry cycles.

Designed for 45 Auto semi-automatic pistols chambered in .45 ACP. .45 Auto is a large-diameter, moderate-velocity cartridge that produces wide wound channels at standard defensive velocities. Low-flash propellant preserves night vision during low-light defensive use — important in the scenarios where defensive ammunition is most likely to be called upon.

Loaded to consistent velocity specifications with tight lot-to-lot controls. The nickel-plated case resists the moisture and corrosion that can develop during extended daily carry, keeping rounds in ready condition over weeks and months in a holster.

Trusted by civilians and off-duty law enforcement for duty sidearm use in 45 Auto platforms. Feeds reliably in compact and subcompact defensive pistols where feed ramp geometry is less forgiving than full-size service pistols.

Hornady Critical Duty is used by law enforcement agencies across the United States — loaded in Grand Island, Nebraska to the same specifications that earned it a place on department approved lists.
