Description
If you've ever squinted at a plain black or brass bead front sight in less-than-perfect light, this is the fix. The Hi-Viz .250" red front sight replaces the factory blade on Smith & Wesson revolvers that use the DX-style interchangeable front sight, giving you a glowing red aiming point that gathers ambient light and delivers it right where your eye needs it. It's one of those small upgrades that makes a real difference the first time you take it out on the range.
What the Hi-Viz Red Front Sight Does Differently
The heart of this sight is the fiber optic LitePipe, and Hi-Viz protects it with a machined body and clear resin overmold that locks the pipe in place. That overmold does two jobs: it keeps the light rod bright by wrapping it in extra clear polymer, and it shields the fiber from the knocks and recoil that come with revolver shooting. The .250" height is measured from the top of the blade to the bottom, not counting the base that seats into your gun, and it's one of three heights Hi-Viz offers so you can match your setup.
Fitting the .250" Front Sight to Your Revolver
This sight drops into Smith & Wesson revolvers built with the spring detent plunger, DX-style interchangeable front sight. Because manufacturing tolerances vary from gun to gun, some revolvers take the sight cleanly while others need a little fitting to seat perfectly. Hi-Viz recommends having a gunsmith handle the install, and that's good advice if you want it done right the first time.
Folks with aging eyes tend to love these, and the follow-up shots get easier when your front sight pops instead of blending into the target. Every Hi-Viz sight is backed by their limited lifetime warranty against manufacturing defects, so you're covered on the build quality. If your S&W wears the right front sight setup, this red LitePipe is an easy way to shoot with more confidence.

Frequently Asked Questions
Will this Hi-Viz .250" front sight fit my Smith & Wesson revolver?
It's built for Smith & Wesson revolvers that use the DX-style, spring detent plunger interchangeable front sight. If your revolver has that removable front blade and needs the .250" height, this is the one. When in doubt, check your model against Hi-Viz's other heights since they offer .208" and .310" versions too.
How is the .250" height measured?
The height is measured from the top of the blade to the bottom, not including the base that seats into the gun. Getting the right height matters because it affects your point of impact. If you're unsure which height you need, matching your existing factory sight is the safest starting point.
Can I install this front sight myself or do I need a gunsmith?
Hi-Viz recommends having a gunsmith install it, and there's good reason for that. Because of small differences between individual firearms, some revolvers accept the sight easily while others need a bit of fitting to seat correctly. A gunsmith has the right tools to get it right without marring anything.
Why choose red over green for a fiber optic front sight?
Red tends to stand out well against green and brown backgrounds, which makes it a popular pick for outdoor and range shooting. Color choice comes down to personal preference and how your eyes pick up each shade. Both red and green gather light and give you that bright, easy-to-see aiming point.
