The Nightstick is a melee weapon in GTA 5 and GTA Online, sold at Ammu-Nation for $400, one of the cheapest items in the store. Like every melee weapon it carries 0 base damage, since melee combat runs on attack animations rather than a bullet value, and it has no fire rate, range or clip figures. As a police style weapon it fits the look of a baton more than an improvised tool, though it swings with the same lock on controls as every other melee item in the game. NPCs typically go down after a short string of hits regardless of what is in your hand, so the practical difference between the Nightstick and pricier melee options is mostly about look rather than effect. It needs no ammo, so the tiny purchase price is the entire cost. There is no Mk II version. At $400 it is barely a dent in a character's budget, making it an easy addition alongside a real firearm rather than a weapon anyone relies on alone.
Buy it from any Ammu-Nation for $400 once you reach rank *I Fought the Law... (GTA V).
