All Critical Defense ammunition is loaded in nickel-plated cases for increased visibility in low-light situations. Premium low flash propellants deliver proven performance, even in very short-barreled handguns, and won’t disrupt your vision. Reliable expansion and dependable terminal performance can be counted on for concealed carry and personal protection. Since their inception, conventional hollow point pistol bullets have performed well, but have never delivered 100% reliability, especially in self-defense situations. The patented Flex Tip technology used in Critical Defense ammunition eliminates the clogging and inconsistency that often plagues hollow point bullets. Hornady achieved this by using the same tip material used in LEVERevolution ammunition.
