HiViz GLLW11 LiteWave Rear Sight for Glock 42/43/43X/48 - Black with Green Interchangeable Fiber Optic

The HiViz GLLW11 LiteWave rear sight for Glock 42/43/43X/48 combines proven fiber-optic technology with a smart new design that puts more light where you need it. The diagonal-wave exoskeleton protects the sight without sacrificing brightness—a real advantage in low-light hunting, range work, or defensive scenarios where acquiring your target quickly matters. If you run a compact Glock and want your rear sight to gather and reflect light from every angle, this is the upgrade that makes sense.

The GLLW11 stands 6.1mm tall, sized precisely for the 42 and 43 platform. That height keeps your sight picture consistent with factory dimensions while the green interchangeable fiber-optic pipe delivers the brightness you're after. The innovative LiteWave geometry exposes more of the fiber to ambient light—sunlight, indoor range lights, or the last bit of dusk—so your sight glows without batteries or tritium. Field-swappable LitePipes (red and black also included) let you adapt to different lighting conditions or just match your shooting style.

Built for shooters who don't compromise on reliability, the HiViz GLLW11 pairs toughness with function. The reinforced exoskeleton keeps the sight intact through holster draws, hard range days, and the occasional fumble, while the exposed fiber-optic design stays true to what made HiViz sights popular: they work, they're bright, and they don't require anything but daylight.

Frequently Asked Questions

What Glock models does the GLLW11 fit?

The HiViz GLLW11 is designed for Glock 42, 43, 43X, and 48. The 6.1mm height is specific to these compact models. If you run a full-size 9mm, .40 S&W, or .357 Sig Glock, you'll need the taller GLLW15 model instead.

Can I swap the fiber-optic colors?

Yes. The GLLW11 comes with green, red, and black interchangeable LitePipes. You can easily swap them to match different lighting conditions or personal preference.

Is this a complete sight set, or just the rear?

This is a rear sight only. You'll pair it with your choice of front sight—whether that's the factory Glock front sight or an aftermarket option.

Do I need batteries or tritium for the sight to work?

No. The fiber-optic design uses ambient light—sunlight, indoor range lighting, or existing light—so there are no batteries to replace or tritium vials to worry about.
