Here's a big dot and a standard dot on J-Frames. I prefer the standard dot because it fits down in the rear notch while the big dot doesn't give a good sight picture because it has to ride above the notch.
I found the same to be true- when the sight radius is short-coupled, the rear notch is frequently problematic with the big dot.
Where I found the big dot more useful was on longer-barreled items, leading me to conclude that they may be too much of a good thing on a pocket gun.

This is how a now retired gunsmith friend fixed the front sight problem for me on my 642-1.
That's an XS Standard Front, dovetailed into the original S&W ramp.
