Buffalo Bore's Heavy 40 S&W +P load uses a flash suppressed powder that gives high velocities at low pressures for a potentially life-saving advantage. More than 90 percent of all human shootings in the USA happen in low light, and you don't want to be blind after you fire one shot in a life-threatening, high-stress situation.
