Some people will say if you can see the opponent you can see the sight, and if you can't see the sight you can't see the opponent anyway.
DO NOT listen to them. Real life lighting is dynamic, and there are situations where ambeint light is in such a condition that you can identify the opponent but you cannot clearly see the dark iron sights.
I always prefer night sights installed on my combat pistols for that reason. However, that's just to be more on the safe side. Non-night sight, just white dots with no glowing inserts may also work when the ambient light is too low for the dark color iron sights to show clear contrast.
