Thought I would try out a set of Ameriglo's new I-DOT style sights. They are comparable to the Heinie Stright eight sights. The fit and finish is excellent, nice coal black color and they went right on with no issues. The front sight is the typical white outline green tritium dot 140x220. The rear is a single smaller and a bit subdued green tritium dot without an outline. The rear sight has a nice 90 ledge to facilitate one handed drills. The rear of the back sight has a slight upward cut to reduce glare. Overall a very nice set of sights The Trijicon name is on the sights as Ameriglo manufactures the bases and Trijicon installs the tritium. I have shot with these a couple of time so far and I find that I can aquire them a bit quicker than my three dots. I ususally prefer the three dot system, but these may have changed my mind. These may stay on my g23 duty pistol. here are a few quick pics I took. TXPO Wanna kill these ads? We can help!
