XS Sights has spent decades building fast sights for pistols, rifles and shotguns, and now the Fort Worth outfit is bringing that work to the wheelgun. The company’s first fiber-optic sights for revolvers are shipping, cut to fit Smith & Wesson J-, K- and L-frame guns.
At the heart of these sights is a fiber-optic front element that pulls in light and throws it back at the shooter’s eye as a bright aiming point. XS leans on U.S.-sourced fiber and an angled design meant to boost light transmission, which pays off most in daylight when a plain black post tends to disappear against a busy background. A standard-size front comes with a green insert installed and an orange rod in the kit, so a shooter can swap colors based on preference or whatever contrasts best downrange.
Installation is straightforward. XS drilled the front sight pinhole at the factory, which means no custom gunsmithing to fit them. Drive out the factory pin, pull the old sight, drop in the XS front, then drive the pin back home. A dab of the included threadlocker holds everything in place. This is the kind of upgrade a confident owner can knock out on a clean bench with basic tools, no drill press or mill required.
“We’re excited to offer our first fiber optic sights for revolvers,” said Jeff King, Marketing Manager, XS Sights. “The special design of the XS Fiber Optic Sights makes them more durable than most on the market and increases the brightness of the aiming point making it an awesome upgrade to any competition, plinking or self-defense revolver.”
Fit spans a healthy chunk of the Smith & Wesson catalog. J-frame .38 Spl./.357 Mag. guns take a front-sight-only kit, while K- and L-frame .38 Spl./.357 Mag. and .44 Mag. models get matched front and fixed rear setups. Owners of adjustable-rear guns like the 586, 686, 625, 629 and 329, plus the newer Lipsey’s 686 and 629 Mountain Gun, can run the adjustable configuration. Buyers who’d rather ditch a wandering adjustable rear for something that stays put can swap to a fixed rear through the same DIY process, and those who want fine windage tuning can opt for a serrated adjustable rear instead.
Paired with the fiber front is a serrated rear, cut to knock down glare and keep the eye from wandering off the front sight. Combined with a wide rear notch, that setup builds a high-contrast picture in bright light and speeds up how quickly the front sight lands in the eye.
Kits ship complete, bundling the front sight, a rear if the model calls for one, both green and orange fiber rods, the pin, a hex wrench where needed, red threadlocker and an insert with instructions. Pricing runs from $59.99 to $118.89 depending on configuration, and the sights carry XS’s limited lifetime warranty.
XS builds these sights from steel and machines them in Fort Worth. For more on fit options and installation, visit xssights.com.
