Hornady's Critical Defense line of defensive handgun ammunition set a new standard in the industry. It was specifically designed to offer a high level of terminal performance, with modest recoil. The FTX bullet was also engineered to expand even after passing through heavy clothing and when fired from short barreled—concealed-carry type—handguns. The 165-grain .40 S&W Critical Defense load is a perfect example of what you can expect from this ammo line. It delivers above average performance for this cartridge.
