Here is an unpopular view point ........but factual.
For CCW work ..........most attacks happen fast [ real fast ] and at close range .......many times close enough to reach out an touch the attacker.
In 99% of these situations, the person being attacked doesn't have time to align "sights" .......... no less ones that glow in the dark!
Point shooting is the most advantageous method to defend oneself in these situations .......... and it doesn't require you to align 3 small glowing dots.
In 1 1/2 seconds .........its all over ............... your response had better be able to match that time limit. Hopefully "Situational awareness" will give you a jump on the "response curve" .......... because VERY few people are good enough to rely on a "fast draw" to save their lives.
Moving to cover ........... is another tactic a CCW shooter must practice at........ trying never to become a stationary target for the attacker. Again, point shooting will give you an edge in being able to move to cover while engaging the attacker.
The [ unpopular ] point I am trying to make here ............ is that in real life - on the streets ......... the need of "night sights" in a self defense situation will be very limited, but not totally un-necessary. Don't be misguided that having them is the save-all in self-defense. Bringing your weapon to bare on your attacker as fast as possible and laying down some fast accurate fire, is best suited to point shooting technics ..........and NOT trying to align 3 small glowing dots on your target. IMHO.
Just another point of view ........ flame suit on
