I use the PF target, the two inch dots are fairly light colored, and it is a problem. I mostly just try to visualize where the dot should be, based on the relative position of the others. I place the edge of my front sight at the base of the target. If I had a drive the dot zero, and it covered the dot, it would very hard.
While it might seem to be a sight alignment exercise, I think it mostly is a trigger control exercise.
