Description
The stock front sight on a Ruger GP100 is a solid black blade, and while it does the job, plenty of folks find it disappears against dark targets or in low light. That's exactly the gap the HiViz LiteWave fills. It's an all-steel replacement front sight built to factory height, so it drops in and lines up with your existing adjustable rear sight without throwing off your zero. The fiber optic pipe soaks up available light and glows, giving you a bright, high-contrast aiming point that's easy to pick up in a hurry.
What Sets the LiteWave GP100 Sight Apart
HiViz built the LiteWave around a diagonal-wave exoskeleton design that protects the fiber while leaving more surface area exposed to gather light from more angles. The result is a genuinely bright bead in a range of conditions. The one-piece steel base has an integral locking system machined right in, so the LitePipe stays put through recoil and rough handling. It's a compact, lightweight piece that carries the same holster-friendly profile as the factory sight.
Three LitePipes, One Sight
What makes this one handy is the color options. It ships with green, red, and white LitePipes plus a changing key that doubles as storage for the spares. Green tends to be the brightest and most popular, red gives great contrast on lighter backgrounds, and white works well in bright daylight. Swapping colors is a quick job with the included key, so you can experiment and settle on whatever your eyes track fastest.
Fitment Worth Double-Checking
Before you order, take a quick look at your revolver. This sight fits GP100 models with an adjustable rear sight and a spring-plunger (spring pin above the muzzle) removable front sight. It does not fit models with a cross-pinned front sight, so give yours a glance to confirm which style you've got. Shooters who've made the swap consistently say the brighter front bead makes a real difference in how fast they find the sight and settle on target.

Frequently Asked Questions
Will the LiteWave fit my Ruger GP100?
It fits GP100 revolvers that have an adjustable rear sight and a spring-plunger retained front sight, meaning the front sight is held by a spring pin above the muzzle. It does not fit models with a cross-pinned front sight. Take a quick look at how your current front sight is secured before ordering to confirm you've got the right style.
Do I need special tools to install the HiViz LiteWave front sight?
On the spring-plunger GP100 setup, the front sight is designed to be removable, so many owners can handle the swap at home with basic care. That said, if you're not comfortable working around the muzzle or the spring plunger, a gunsmith can do it in a few minutes. The included key handles the LitePipe color changes with no other tools needed.
Which LitePipe color should I use?
It comes with green, red, and white, and the best one really comes down to your eyes and your typical background. Green is usually the brightest and the crowd favorite, red gives strong contrast on lighter targets, and white holds up well in bright daylight. You can swap them in seconds with the changing key, so try each and keep whatever you pick up fastest.
Will this LiteWave sight change my point of impact?
The LiteWave is built to factory height, so it's designed to line up with your existing adjustable rear sight without changing your zero. Since the GP100 rear sight is adjustable, any minor tweak is a quick fix at the range. Most owners find it drops right in and shoots to the same point as the stock front sight.
