Trigger Discipline

 is a Trait which only appears in Fallout: New Vegas. This trait most benefits stealth and long range combat style characters. However, as a character levels, weapon skills rise, and accuracy naturally increases, the accuracy granted by this trait seems to be less needed, while you retain the loss of fire rate and less VATS shots. FPS styled players will find the trait useful throughout the game, as it turns many early pistols into mid or long-range sniper platforms when compared directly to a pistol without use of the trait (can hit enemies so far away their health will not display and must rely on Crippled Limb/Sneak Attack notifications to tell if you are even hitting the target).

This trait can also be used to reduce the ammunition consumption on weapons such as the Laser RCW or other rapid fire weapons, helping the heavy fingered player conserve ammunition outside of VATS.
