u can't MISS seeing good luminous sights at night. IPSC RARELY fires any shots as close as 10 ft, and 10 ft is about max range for justifiable civilian self defense, and yes, you sure can miss the chest, repeatedly, at 6 ft or so, if you dont have some sort of sight reference. In daylight, you have at LEAST the silohuette of your hands and the gun as a rough "sighting tool". At night, you have nothing of the kind.
