Grenade Launcher (Fallout: New Vegas)

The Grenade Launcher is a weapon $$

Gameplay
The grenade launcher is a pump-action operated weapon, firing 40mm Grenades from a tubular magazine. Despite being only slightly larger than the Grenade Rifle, it weighs twice as much.

Durability
The Grenade Launcher can fire a total of about 495 standard rounds, the equivalent of 124 reloads, from full condition before breaking.

Locations

 * Can be found at Nellis Air Force Base and on most Boomers, including Pearl.
 * The munitions trader at Nellis Hangars sells them.
 * Two of them can be found in the armory of Vault 34 in poor condition, along with some 40mm Grenade ammunition.
 * Grenade Launchers can also be purchased from Daniel Contreras at the Camp McCarran Supply Shack or from Blake at the Crimson Caravan Company.
 * One can be bought from the NCR Arms Merchant at the 188 Trading Post.
 * They can be found on some of the White Legs tribals.
 * There is one carried by one of the caravan guards at the beginning of the trip to Zion Canyon.
 * A good condition Grenade Launcher can be found at the top of a large, tall rock between the X-2 Transmitter Antenna Array and Higgs Village.

Behind the scenes
According to Joshua Sawyer, the Grenade Launcher is based on the real-world China Lake grenade launcher.
 * Dead Money changes the repair list from "RepairNVGrenadeLauncher" to "RepairMinigun," which despite its Editor ID, still features only the Grenade Launcher in the list. The Editor ID of the repair list for the Minigun is "RepairMinigunForRealzImSeriousGuys" even in the base game.

Bugs

 * Dead 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, its attack shots/sec is increased to 0.5556, and the flag that makes non-player characters use ammo is lost.
 * In V.A.T.S., you may fire 2 or more shots at an enemy, if the first one succeeds to kill the enemy, the other shots will still be fired, rather than exiting V.A.T.S. when the kill is completed, wasting ammunition and time.
