Not in my opinion. Of course I've only been in one nighttime armed confrontation in my entire life; and, quite honestly, after it was over I would have preferred for that big brightly glowing green Meprolight front sight NOT to have been there obstructing my view of the target.
Knowing now what I didn't know then I much prefer an older duller set of, 'night sights' or something small like the size of George Heinie's, 'Straight Eight' night sights. Heinie has said that he put a lot of thought into the design of his night sights; and, personally, I believe him.
