Ameriglo Green Tritium Lime Lumi Round Outline Front .165''H .125''W

The AmeriGlo Green Tritium Lime Lumi Round Outline Front sight is a pistol front sight designed for shooters who want reliable low-light aiming without batteries or recharging. This tritium front sight pairs self-illuminating tritium vials with a lime-green outline that captures ambient light, giving you visibility options in bright daylight and deep shadow alike. The round outline design helps frame your target while the green tritium core glows on its own in darkness—ideal for home defense, low-light range work, or any scenario where you need quick, confident sight pictures regardless of lighting conditions.

AmeriGlo's tritium + LumiGreen combination has become popular among shooters who've ditched battery-dependent sights or wanted a backup to electronic optics. The compact dimensions (.165" height, .125" width) fit standard Glock dovetails, making installation straightforward on most modern Glock platforms. The green tritium and lime outline create excellent contrast against typical indoor and outdoor backgrounds, and the self-luminous tritium means your front sight never fails due to dead batteries or failed electronics.

Whether you're setting up a duty rig, a home-defense pistol, or a range gun, a quality tritium front sight is one of the smartest upgrades you can make. This AmeriGlo sight delivers the visibility and durability that have made tritium sights the standard in professional and civilian defensive work for decades.

Frequently Asked Questions

Will this tritium sight work on all Glock models?

This sight is designed for Glock dovetail mounts, which fit most modern Glock platforms. If you're unsure about your specific model, check your gun's manual or contact us before ordering.

How long does the tritium glow last?

Tritium has a half-life of about 12 years, meaning it will glow dimly even after that period, though with reduced brightness. The exact lifespan depends on environmental factors and storage conditions.

Can I use this sight in bright daylight?

Yes. The lime-green LumiGreen outline is designed to be visible in daylight and will provide a clear sight picture in strong ambient light. The tritium core supplements this in low-light conditions.

Does this sight require any tools or special installation?

Installation requires a Glock front sight tool or appropriate pusher to remove the dovetail screw and install the new sight. We recommend consulting your Glock manual or a qualified gunsmith if you're unfamiliar with the process.
