Ameriglo Pro-Glo Tritium Round Front Sight .200X.140 Org For Glock~

The AmeriGlo Pro-Glo tritium round front sight brings reliable low-light performance to any Glock pistol. Built from bar-stock steel and designed with law enforcement and military use in mind, this front night sight uses a self-illuminating tritium lamp that glows consistently for up to 20 years without batteries or ambient light—ideal for defensive shooters who need their gun ready in any conditions. The .200-inch sight post height and .140-inch width fit standard Glock dovetails across the full Glock lineup, making it a straightforward upgrade for shooters who want to shoot fast and confident when it matters.

What sets the Pro-Glo apart is its dual-plane luminescence: the tritium lamp itself emits a green glow, while the sight post is ringed with luminescent orange material that charges from any available light and glows on demand. This combination gives you both passive nighttime visibility and a bright aiming point in low to no-light scenarios without the maintenance of battery-powered electronics or the learning curve of reflex sights. Steel construction means it'll hold zero through hard use and recoil, a priority for duty weapons and serious defensive carry.

Whether you're upgrading a duty gun, improving a home-defense Glock, or building a range rig you can trust in low light, the Pro-Glo puts a genuine night sight upgrade within reach. Installation requires a front sight pusher or smith visit, but once in place, you've got two decades of reliable luminescence without worrying about batteries dying or tritium levels fading fast.

Frequently Asked Questions

Does the AmeriGlo Pro-Glo fit all Glock models?

Yes. This sight fits all Glock pistol models via the standard dovetail cut. Verify your front sight post height and width match your Glock's cut, and you're ready to install.

How long does the tritium glow last?

The tritium lamp is rated to produce visible illumination for up to 20 years without batteries, charging, or maintenance. After that time, the lamp will gradually dim but the sight remains fully functional as an iron sight.

Do I need batteries or a charger for this sight?

No. The tritium lamp is completely passive and requires no power source. The orange luminescent ring will charge from any ambient light and glow on its own, but the green tritium provides nighttime visibility independently.

What's the difference between the tritium and the orange ring?

The tritium lamp itself glows green in darkness for 20 years. The orange luminescent ring surrounding it charges from daylight or indoor light and glows bright in low-light conditions. Together they give you reliable aiming points in any lighting scenario.
