Trigger Discipline

 is a Trait which only appears in Fallout: New Vegas. This trait most benefits Rambo style play over those who prefer to snipe. However, as with Fast Shot, the downside becomes more and more prominent as your character levels, weapon quality increases, and skills increase.

As said before, this trait is better suited to players who prefer fully automatic weaponry over those who like to snipe. For example, the Anti-Materiel Rifle has a spread of 0.03, and this perk would only reduce the spread to 0.024, which is a difference far too small to detect. In fact, even on the absolute lowest sensitivity settings, adjustments to ones aim, on a mouse or controller, are not even possible at such a small scale. Most scoped weapons have extremely low spread values, rendering the accuracy benefit useless, for all intents and purposes, on nearly any "sniper" weapon, while still retaining the full negative aspects of the reduced fire-rate.

Looking at automatic weapons is a different story entirely. Automatic weapons tend to be very inaccurate, while going through an entire magazine very quickly, and in the process wasting several bullets that simply did not hit the target by no fault of the user. With this trait, automatic weapons are dramatically improved, and because of the increased accuracy, damage outside of vats remains roughly the same, increasing the further away your target is.

This perk does not affect the spread increase for standing or moving, which again makes it have almost no positive effect on weapons that already have low spread. It only modifies the weapon's base spread value.

Note

 * If used with Fast Shot, the penalties and benefits negate each other.
