The AMERIGLO i-Dots are some of our favorite iron sights. The front sight is high visibility orange making it very easy to maintain focus, or super-impose on a target while using a hard-target focus technique. A tritium ampule is nested inside the high visibility orange front sight, and another is located in the rear below the notch. The sights can be used for low/no-light shooting and even with NVGs (although it’s a sub-optimal sighting solution).

How do I install these?
To install the front sight, you’ll want to purchase a Glock Front Sight Tool and use a drop of blue Loctite.
For the rear iron, you can use a brass punch and hammer, but it is very difficult to do, let alone do it accurately. The best tool for the job is a Wheeler Engineering Sight Tool. This is what we use in our armory. They are pricey, but a wise investment. Get a couple of buddies or family members that can all benefit from using it, have them pitch in, and it becomes a “community” tool that you can use to install / uninstall / tweak just about any iron sight on any handgun.

What’s the difference between these AMERIGLO night sights and the Trijicon HD XR Night Sights?
The Trijicon Night Sights have a three-dot aiming system as opposed to the two-dot system on the AMERIGLO i-Dots. The Trijicon sights also have a thinner front sight post (0.122″ vs. 0.140″).
