Meprolight Tru-Dot Front Sight for Ruger SP101 - Tritium Green

SP101 Tritium Front Sight

The factory front sight on a Ruger SP101 is a plain black blade, and in poor light it is hard to see. This Meprolight Tru-Dot replacement puts a green tritium dot on the front of the blade so you can find your front sight in a dark room, at dusk, or anywhere the black blade disappears against the target. It suits SP101 owners who keep the revolver for home defense, concealed carry or field use.

Features

• Green Tritium Insert — Tritium is a radioactive gas that glows on its own, so the dot is visible in darkness without batteries, switches or charging in light first.
• White Ring Surround — A white ring around the tritium vial gives the dot a visible outline in daylight, when the glow itself is hard to see.
• Steel Construction — The blade is machined from steel rather than polymer, so it holds up to holster wear and handling.
• Blued Finish — A dark blued finish, a traditional chemical treatment for steel, keeps the blade black and non-reflective so only the dot draws the eye.
• Ruger SP101 Specific — The blade is shaped for the Ruger SP101 double-action revolver and replaces its factory front sight.
• Single Front Dot — With one bright reference point at the muzzle end, you can put the dot on the target quickly when aligning sights is difficult.
• Model Marking — The side of the blade is stamped MH3 for identification.

Fit And Construction

This is a front sight only, made by Meprolight for the Ruger SP101 and sold as a single blade. The body is solid blued steel with a curved base that matches the revolver's front sight mount, and the tritium vial sits flush in the rear face where the shooter sees it. Tritium glow fades gradually over a period of years, so the dot is brightest when new.
