Trijicon now offers both Bright and Tough and HD Night Sights for the Smith & Wesson M&P Shield.

Highly effective at close quarters, Trijicon HD Night Sights are designed to excel under the most demanding conditions by placing primary emphasis on faster front sight acquisition. This new design incorporates enhanced front sight visibility with a de-emphasized rear sight. Upfront, a tritium lamp lies within an extra-large, brightly colored (yellow or orange) dot area that provides a distinctive sighting picture. In addition, special photo luminescent (glow-in-the-dark) powder in the paint aids in faster front sight acquisition during transitional lighting operations.

Trijicon Bright and Tough self-luminous Night Sights increase night-fire shooting accuracy by as much as five times over conventional sights. Equally impressive, they do so with the same speed as instinctive shooting- and without the need for batteries.
