AmeriGlo Pro GLOCK 20/21/29/30/31/32/36 I-Dot Sight

I-Dot Night Sight Set

This AmeriGlo Pro I-Dot set replaces the factory sights on the larger-frame Glock pistols: models 20, 21, 29, 30, 31, 32 and 36. The front sight carries a bright orange ring around a tritium insert. The rear has a single tritium dot under the notch. In daylight your eye goes straight to the orange front. In the dark, the front dot sits on top of the rear dot and forms a lowercase "i", which is a quick sight picture to learn for carry or home defense.

Features

• I-Dot Configuration — The front dot stacks vertically over the single rear dot, so you line up two dots in a column instead of three in a row.
• Tritium Inserts — Both sights are marked H3, the symbol for tritium, a self-luminous gas that glows in low light without charging from a flashlight or the sun.
• Orange Front Outline — A wide orange ring around the front insert stands out against most backgrounds in daylight.
• White-Ringed Rear Dot — The rear tritium dot sits below the notch inside a thin white ring, so it reads as a reference point without competing with the front.
• Square Rear Notch — A flat-bottomed, square-cut notch gives the front post clear light on either side for an even sight picture.
• Black Matte Finish — The sight bodies are finished in black to keep glare down around the dots.
• Large-Frame Glock Fit — The set is built for the Glock 20, 21, 29, 30, 31, 32 and 36, which share the same sight cuts.
• Front And Rear Included — You get a matched front and rear sight, so the heights are set up to work together.

Fit And Construction

The rear sight has a dovetail base, a wedge-shaped foot that slides sideways into the matching slot on the Glock slide, and the front post sits in the factory front sight position. Each sight is laser-marked with the AmeriGlo name and H3 code. These sights are not made for the standard-frame 9mm and .40 models such as the Glock 17, 19 or 22, so check your model number before ordering.
