Frequently Asked Questions
Which S&W M&P models are these Trijicon HD sights compatible with?
These Trijicon HD night sights are designed to fit the Smith & Wesson M&P full-size and compact pistol series, including popular chamberings in 9mm, .40 S&W, and .45 ACP. They are not designed for the M&P Shield or M&P Shield Plus, which require a different sight cut. Always verify your specific model's sight dimensions before ordering.
What is the advantage of a yellow front sight over a standard green tritium front?
The yellow tritium lamp on the front sight creates a high-contrast color distinction between the front and rear sights, allowing your eye to instinctively pick up the front sight faster — especially in transitional or low-light scenarios. Many shooters and law enforcement trainers prefer yellow or orange front lamps because they are more quickly discernible under stress and in dynamic shooting environments.
How long will the tritium vials last, and do the sights require any maintenance?
Trijicon's tritium vials have a rated illumination half-life of approximately 12 years, meaning they will continue to provide usable glow well beyond that period — just at reduced brightness. The sights require no batteries, charging, or maintenance. The tritium is hermetically sealed within the sight housing, and the hardened steel construction resists damage from recoil, solvents, and everyday carry wear.
