Highly recommend! - Trijicon Heavy Duty Night Sight Set, Yellow Front Outline, Springfield XD-S

I love these sights! Target acquisition is quick and accurate. The sights are durable and bright! They are good to go day, night, dusk or dawn. I had them for over a year. This is my Every Day Carry XDS 9mm. I had the sights installed by a professional gunsmith and will continue to do so. It is worth the cost.
