I love my night sights, My husband has a flashlight connected to his gun. But I asked for night sights because I wear contacts. But take them out at night, so if I ever had to defend myself with out my contacts in, I needed the night sights. I have excellent muscle memory and don't have to look to get my sights aligned, but when you're frazzled, who knows what will happen...
So, I have my night sights and they glow so awesome that I can seem them very well even though I am blind as a bat without my contacts.
Definitely worth the money for me.
