HIVIZ WIDE MAG SG RD .328-.437""
The Hi-Viz Wide Mag SG front sight (.328-.437" width) is a replacement front sight designed to pair with your factory rear sight and deliver fast, reliable target acquisition in variable light. Built with a machined steel body and Hi-Viz's proven overmolded LightPipe technology, this sight gathers ambient light and channels it through a protected polymer core—ideal for hunters and shooters who need to stay on target from dawn to dusk. The wide mag profile fits Smith & Wesson revolvers and pistols with 2.5-inch or longer barrels and adjustable rear sights, making it a practical upgrade for shooters who want their sighting system to work harder in the field.
Hi-Viz's overmolding process wraps a clear polymer layer over the light-gathering LightPipe, shielding it from impact and abrasion while maintaining the bright, fast-acquisition advantage that makes these sights popular with hunters and defensive shooters. The wide mag design accommodates a broader sight plane, giving you more reference surface when aligning your shot. Installation height is .269 inches, and gunsmith fitting is recommended to ensure proper function and regulation with your specific firearm.
Compatibility note: This sight is designed for most Smith & Wesson models with 2.5-inch or longer barrels and adjustable rear sights. It does not fit classic series or Performance Center guns, and it requires a pinned front sight mounting. Before purchase, confirm your gun's rear sight type and barrel length—fitting by a qualified gunsmith will ensure the sight is installed correctly and your gun shoots to point of aim.
