"If you are like me, you were not finding many options for night sights for the FNP 9 or FNP 40. These sight work good, but the front sight illumination is smaller than the rear, slowing the sight acquisition in low light situations. Day time they work great as there is a white ring around the tritium that is easy to acquire."

"AmeriGlo is the only one making night sights for the FNP models, it makes it harder to choose the brand you want to use. All in all these sights are good. The reason I gave it 4 stars, is they could stand to be a little more brighter. They do help in low light conditions. I didn't have any trouble with reacquiring target acquisition. They work good."
