Then why not just use iron sights? The whole point of a dot is that the dot does not need to be centered, the POI is always behind the dot. So you are either centering the dot, which slows you down, or you are point shooting with your other eye dominant.
I was well trained in point shooting, by people who learned from people who learned directly from Applegate. I kept hitting the instructors' gun hand with the simunitions. Proving that you not only hit what you look at, you tend to look at the threat.
I agree, you hit what you're looking at, and this helps me do just that at a faster pace.
It's one of those things you just have to use to see the difference in not using one.
This is coming from a practical sport shooting perspective, not a defensive one.
When drawing and transitioning you should look for the streak of a dot to appear on the target you're already looking at.
Most will naturally follow the dot to the target, which is significantly slower. I look at the target first and then tell the dot to get there.
That cover helps me better do that and speeds up my draws and transitions.
