Arquebus, or Harquebus, an early firearm. Several types of firearms were known by the name arquebus during the 16th and 17th centuries. All were fired from the shoulder or chest. The firing mechanism was originally a matchlock, a device that held a piece of burning wick and touched it to the powder in the gun when a trigger was pulled. Later, other firing arrangements were used.
The revolver turned shooting a round into a one-step process, forever changing the face of crime, law enforcement and self-defense. Find out what goes on inside a revolver.
