Practical shooting is a sport that evolved from
experimentation with handguns used for self-defense. The
researchers were an international group of private
individuals, law enforcement officers, and military people
generally operating independently of each other, challenging
the then-accepted standards of technique, training
practices, and equipment. The work was, for the most part,
conducted for their own purposes without official sanction.
Even so, what they learned changed the face of police and
military training forever.
