Here is a dumb question; why are there different sights for carry vs competition? Aren't both shooting styles focusing on quick shots to a larger target than say a precision shooter?
I recently switched to XS Big Dots on my EDC. The thinking is that the big front sight will be easier to pick up quickly on a close range human sized target. Simply dot the eye. Both front and rear contain tritium and glow green at night.
They are great for under 15 yards, but aren't really suited for competition or precision shooting because it's tough to hit small targets beyond that. The large front dot covers so much of the target.
