A box of 20 rounds, the Hornady Critical Defense .40 S&W 165gr FTX Ammunition (Hornady part no. 91340) is a .40 S&W load carrying a 165-grain FTX bullet. The bullet comes from Hornady, whose patented Flex Tip technology is meant to expand reliably and resist clogging when fired through heavy clothing. Hornady publishes 1045 fps and 400 ft-lb at the muzzle from a 4-inch test barrel. At 100 yards the same load is listed at 914 fps and 306 ft-lb. Hornady aims the line at concealed carry and personal protection, including very short-barreled handguns.
