The Hi-Viz GLN621 LiteWave H3 fiber-optic sight set brings reliable visibility to your Glock 42, 43, 43X, or 48—whether you're at the range, in the field, or carrying daily. This dual-illumination system pairs a fiber-optic front sight with a tritium rear sight, giving you bright, quick target acquisition in daylight and low-light conditions without relying on batteries.
The green tritium rear sight maintains visibility when ambient light fades, while the orange fiber-optic front post captures and channels available light for a glowing sight picture in bright conditions. The orange outline framing both sights creates a defined sight plane that helps your eye naturally center the picture. LiteWave technology integrates these illumination methods so you get fast sight pickup whether you're shooting in noon sun or dusk.
These sights are purpose-built for Glock's compact and subcompact frames—a natural fit for defensive and carry shooters who want faster target location than standard three-dot sights without the maintenance or battery concerns of electronic optics. Installation is straightforward on compatible Glock models, and the robust construction handles regular use and training without fuss.
| Sight Set Type | Fiber-optic front / tritium rear |
| Compatibility | Glock 42, 43, 43X, 48 |
| Front Sight Light Source | Fiber-optic with orange litepipes |
| Rear Sight Light Source | Green tritium |
| Outline Color | Orange |
| Model | GLN621 |
The GLN621 is designed for Glock 42, 43, 43X, and 48 models. Confirm your Glock model before purchase to ensure compatibility.
The fiber-optic front sight glows bright in daylight by collecting ambient light, while the tritium rear sight self-illuminates in darkness without external power. Together they give you a bright, fast sight picture in both day and low-light shooting.
No. Fiber-optic sights use natural and ambient light, and tritium is a self-illuminating isotope that requires no batteries or charging. This makes them reliable for any shooting condition without maintenance.
The set includes a fiber-optic front sight with orange litepipes and a green tritium rear sight, both with orange outline frames, configured and ready for installation on compatible Glock models.
