Ameriglo Pro-Glo Tritium Round Front Sight .220X.140 Grn For Glock~

The AmeriGlo Pro-Glo Tritium Round Front Sight is a self-illuminating night sight built for Glock pistols that need reliable aiming reference in low-light and darkness. Whether you're training after hours, carrying for home defense, or preparing for any scenario, this front sight delivers the 24-hour visibility that separates a defensive handgun you can actually use from one you can't. The sight features genuine Swiss tritium that glows continuously without batteries—good for roughly 20 years of operation.

What makes the Pro-Glo stand out is its design logic: the tritium lamp is surrounded by a bright green luminescent ring that charges from ambient light and provides exceptional daylight sight picture. In darkness, the tritium takes over. You get fast, intuitive target acquisition whether you're shooting in bright sun, dim indoor light, or complete blackness. The rounded profile reduces snagging and feels natural in the hand during draw and reholster.

The sight blade measures 0.220 inches in height and 0.140 inches in width, machined from bar stock to Glock's exacting tolerances. Installation requires basic gunsmithing—front sights are not user-swappable on most Glocks—but once fitted, this sight will outlast many handguns. It's the choice of shooters who treat their sights as a critical system, not an afterthought.

Frequently Asked Questions

Will this front sight fit my Glock?

Yes, the Pro-Glo is designed to fit all Glock pistol models with standard front-sight dovetails. Installation requires removing the existing front sight and fitting this one in its place; this is best handled by a qualified gunsmith unless you have sight-pusher experience.

How long does the tritium glow last?

The Swiss tritium lamp has a useful lifespan of approximately 20 years. It requires no battery, charging, or external power source—it self-illuminates continuously from the tritium decay process.

What's the green ring around the tritium for?

The green luminescent ring charges from ambient daylight and provides excellent sight visibility in bright conditions. When darkness falls and ambient light fades, the tritium orange lamp becomes your reference. This two-mode design gives you fast, usable sights in any lighting condition.

Is this a front sight only, or does it come with a rear?

This is a front sight only. You will need to source a compatible rear sight separately to complete a full night-sight setup for your Glock.
