The Meprolight Hyper-Bright Green Tritium Orange Outline Front Sight-Green Tritium Black Outline Rear for Smith & Wesson M&P Shield delivers industry-leading visibility in any light, thanks to tritium formulated for maximum brilliance from broad daylight to midnight. These fixed, self-illuminated sights feature a highly visible colored ring front sight in green and orange to deliver fast target acquisition, with a contrasting rear that helps your focus settle quickly on the front sight in all conditions. The yellow ring option adds a phosphorescent charge that glows in low light, enhancing daytime and nighttime performance when used in conjunction with the tritium. Always-on illumination requires no batteries or switches, providing ready, instant sight picture for 12 years, while a durable steel build offers drop- and shockproof reliability under heavy recoil and adverse weather. The U-notch rear naturally directs attention to the top of the front sight, supporting instinctive aiming during high-pressure moments. Designed as a direct factory replacement, these matte-finished sights provide a true day-night advantage and are ideal for fast, precise draws on the M&P Shield platform.
