Ameriglo Glock 42 and 43 I-Dot Sight Review

Let’s Talk About Ameriglo Glock 42 and 43 I-Dot Sight

The Ameriglo Glock 42 and 43 I-Dot Sight is designed to improve target acquisition speed and accuracy in Glock’s slimline pistols. Ameriglo is a well-known name in the aftermarket sight industry, and their I-Dot configuration is popular for its intuitive dot-over-dot alignment. The combination of a bright front sight and a simple, single-dot rear is intended to simplify the sight picture, especially in stressful situations.

After years of using three-dot sights, I found myself searching for a simpler and faster sighting system for my Glock 43. The three-dot system, while familiar, sometimes felt cluttered. I was hoping the Ameriglo I-Dot would streamline my focus on the front sight, improving my shot groupings and speed.

The sights arrived in a small, unassuming package. Upon opening it, the first thing I noticed was the brightness of the front sight; the lime green outline around the tritium vial really pops. The rear sight, with its single green tritium dot, looked clean and purposeful. The overall build quality seemed robust, what I would expect from Ameriglo.

I considered other options, including the Trijicon HD XR and the XS Sights Big Dot. I chose the Ameriglo Glock 42 and 43 I-Dot Sight because I wanted to try the vertical alignment method, and the price point was attractive compared to the others. It was a calculated move towards a less cluttered sight picture.

Initially, I was cautiously optimistic. The sight picture looked promising, but I was unsure how it would translate to real-world performance at the range. I hoped they’d live up to the hype.
