At a match, the first shot often exposes a presentation problem before it exposes a marksmanship problem.
A competition handgun with a slide mounted optic must arrive at the same visual reference point on every draw. If the window appears high, low, or off to one side, the shooter may spend the opening fraction of a second hunting for the dot.
That delay is usually tied to grip angle, wrist position, or an inconsistent holster presentation. A red dot does not repair those habits. It makes them easier to see under pressure.
