The Nightstick is a melee weapon assigned to each cop in the GTA III Era since Grand Theft Auto: Vice City as a standard melee weapon. Although not as powerful as the Baseball Bat, it has an advantage of being a single-handed weapon and thus 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 a spawning point. A nightstick is seen in the GTA V trailer when the LSPD are chasing a suspect which leads to the possibility of being a weapon. Nightstick is a law enforcement T-Baton, believed to be based on the Monadnock PR-24 Control Device Baton, with the exception that the Monadnock's version is retractable.
- The Nightstick is the only weapons that does not have a spawning location in Grand Theft Auto: Liberty City Stories.
