Trigger Happy
Trigger Happy increases fire rate. It changes a firearm property rather than directly increasing the ranged damage, critical hit, or reload effects documented for other Traits.
How it works
The Traits source says Trigger Happy increases Fire Rate by 1% per Trait Point invested and lists a maximum of 20%. The same source separately describes Mind's Eye as increasing ranged damage and Quick Hands as increasing weapon reload speed, so those effects should not be conflated.
When it helps
Consider Trigger Happy if fire rate is the firearm property you want to improve. If you want ranged damage or faster reloads, compare Mind's Eye or Quick Hands, whose effects are separately described.
The tradeoff
The documented change is fire rate; it does not state that the Trait increases damage per shot or reload speed.
Your next step
Check whether fire rate, ranged damage, or reload speed is your intended firearm priority before allocating Trait Points.
