My Elite Series 2 Trigger Stops Make The Triggers Feel Inconsistent

This is a real effect and in most cases it is tolerance rather than a fault, but there are two things to check that genuinely do cause it.

The trigger stops on an Elite Series 2 are a purely mechanical limiter: a cam that shortens the physical travel of the trigger. The electrical actuation point does not move. So at the shortest stop setting, the trigger has very little travel left, and any small difference between the two sides, in the cam position, the trigger's return spring tension, or the sensor's own calibration, becomes proportionally much more noticeable. At the longest setting the same difference is spread over three times the travel and you would never feel it. That is why this only appears at the shortest position, and it is the usual explanation.

The two real causes worth ruling out. First, the lock is not fully engaged on one side. The stop mechanism clicks between positions and it is entirely possible to leave one side sitting between detents, which gives you a slightly different travel on that trigger. Push both to the shortest position firmly and confirm you felt the click on each. Second, a profile. The Elite stores trigger settings per profile, and a profile with a different trigger range or curve applied to one side will do exactly this. Check the Xbox Accessories app for an active profile and compare the left and right trigger settings in it.

If both sides are locked and the profile is clean and the difference persists, then you are looking at tolerance or early wear in one trigger's return spring. For competitive play my honest recommendation is to move both stops one position longer. You lose very little actuation speed and you get consistency between the two sides, which matters more than a millimetre of travel.
