Nightstick

The Nightstick is a melee weapon assigned to each cop in Grand Theft Auto: Vice City, Grand Theft Auto: San Andreas, Grand Theft Auto: Liberty City Stories, Grand Theft Auto: Vice City Stories, and Grand Theft Auto V as a standard melee weapon. While having the same attack power as the Baseball Bat, it has an advantage of allowing a quicker running speed. It cannot be purchased from hardware stores or Ammu-Nation. Therefore, it is only obtainable from killing a cop or finding it at spawn points.
