Hornady Critical Defense Features Hornady Critical Defense was developed to provide the best performance for personal protection situations and is the ultimate choice for short-barreled concealed-carry style firearms. Nickel-plated cases resist corrosion and simplify chamber checks in low light. Optimized propellants burn quickly to reduce recoil and limit muzzle flash preserving night vision. The patented Hornady FTX bullet with its Flex Tip expands reliably and resists the clogging and inconsistency that often plague other hollow points when fired through heavy clothing. Critical Defense performs especially well in close-quarters and short-range situations.
