A pump-action weapon with a tubular magazine holding four 40mm grenades, the grenade launcher is an excellent tool for delivering explosives over long distances. Leaf iron sights similar to the grenade rifle are mounted on it. The front sight is a fixed square notch.
There is one carried by one of the caravan guards at the beginning of Honest Hearts.
Notes
Characters with high agility and/or Rapid Reload may prefer the lighter and simpler grenade rifle, as with quick reloads it can fire faster than the grenade launcher.
Prior to patch 1.4.0.525, the grenade launcher could be repaired with miniguns. Miniguns cannot be repaired with grenade launchers, even with Jury Rigging.
PCPlayStation 3Xbox 360Dead Money overrides some of the changes that have been made to the grenade launcher in previous patches. With Dead Money installed and nothing else taking up space in your load order, the grenade's base damage is increased to 30, its spread is increased to 1.0, non-player characters will still use ammunition, and it can still be repaired with miniguns.
