AmeriGlo I-Dot 2 Dot Sights for Glock

i-Dot Tritium Night Sights

The AmeriGlo GL102 is a front and rear night sight set for large-frame Glock pistols: the Glock 20, 21, 29, 30, 31, 32 and 36. It replaces factory sights that can disappear in poor light with two tritium inserts that glow on their own. This is a practical upgrade for anyone who carries or keeps one of these pistols for home defense, where low-light shooting is a real possibility.

Features

• Tritium Inserts — Each sight carries a vial of tritium, a gas that glows green continuously in the dark with no batteries or light charging required.
• i-Dot Sight Picture — With the sights aligned, the front dot sits directly above the single rear dot, forming a lowercase "i" that is quick to read.
• White Outline Front Ring — A white ring surrounds the front tritium vial so the front sight stands out in daylight as well as at night.
• Single-Dot Rear Sight — One dot set below the notch keeps the rear quiet, so your eye goes to the brighter front sight first.
• Square Rear Notch — A flat-bottomed notch gives clear light on either side of the front post for precise alignment.
• Screw-On Front Sight — The front sight secures through the slide with a hex fitting, the same attachment style Glock uses at the factory.
• Dovetail Rear Sight — The rear slides into the standard Glock dovetail, the angled slot cut across the top of the slide.
• Matte Black Finish — A non-reflective black finish on both sights cuts glare across the top of the slide.

Fit And Compatibility

The GL102 is sized for the Glock 20, 21, 29, 30, 31, 32 and 36, which covers the 10mm, .45 ACP and .357 SIG models in full-size, compact and subcompact frames. It will not fit the smaller 9mm and .40 S&W slides, which take a different sight set. Both sights are laser-marked with the AmeriGlo name, and the set includes the front and rear sight together.
