Night Fision Tritium Night Sights for Glock - Black | Green Tritium Yellow Ring Front, Green Tritium White Ring Rear (GLK001007YGW)

Night Fision's Perfect Dot tritium night sights for Glock pistols bring self-illuminating visibility to your carry gun in any light. This specific set pairs a green tritium front sight with a yellow ring around the dot for daylight acquisition, backed by a green tritium rear sight with a white ring. The front sight sits brighter than the rear—a purposeful design choice that encourages solid front-sight focus when speed matters. Whether you're training on the range, carrying for personal defense, or running a night course, these sights keep you oriented on target fast.

Night Fision engineered the Perfect Dot with 30% more tritium than conventional night sights, delivering noticeably vivid glow in low light. The tritium is surrounded not by painted rings but by a daylight-fluorescing material, so you get crisp sight picture in bright conditions too. The result is sights that stay visible whether you're shooting in daylight, dusk, or complete darkness. A reinforced mounting system locks the tritium vial securely in place, protecting it from recoil stress and rough handling. The 4140 steel housings wear a matte black nitride finish that resists wear and corrosion—built to last through carry and use.

This set fits standard-frame Glock pistols (G17-size dimensions) at factory height, making installation straightforward on most full-size and mid-size Glock models. Night Fision offers these sights as matched front-and-rear pairs only; you can't buy them individually. If your Glock runs a suppressor, Night Fision makes a dedicated suppressor-height version, though this set is factory height.

Frequently Asked Questions

Will these sights fit my Glock?

These Perfect Dot sights are machined for standard-frame Glock pistols (G17-size) at factory height. They fit models including the G17, G19, G22, G23, and similar full-size and compact Glocks. If you own a Glock 42, 43, or a Glock equipped with a suppressor, Night Fision makes separate models for those platforms. Always verify your specific model before ordering.

Do these night sights glow in the dark without batteries?

Yes. Night Fision Perfect Dots use self-illuminating tritium, which provides a continuous glow in low light without batteries, charging, or activation. The tritium never needs attention—it simply works. You'll see a faint glow in daylight and a much brighter, vivid glow in darkness and low-light scenarios.

What's the difference between the front and rear sights on this set?

The front sight features a green tritium dot surrounded by a yellow daylight-fluorescent ring and glows brighter than the rear. The rear sight has green tritium dots on either side of the notch with white fluorescent rings. This brightness difference is intentional—it helps your eye naturally favor front-sight focus, which is the foundation of accurate shooting under pressure.

Why use a fluorescent ring around the tritium instead of paint?

Night Fision's fluorescent material provides superior daylight visibility compared to painted rings. Combined with the tritium underneath, this design delivers the "Perfect Dot"—maximum sight picture clarity in both bright sun and total darkness. It's one of the reasons these sights stay on target faster than conventional tritium-only designs.
