Ameriglo gl-112-180 tritium front sight - Ameriglo Green Tritium Night Sights - Front Only

This is just what I expected and needed. .180 height, .125 width, with a small tritium dot inside a white ring. The craftsmanship seems very high quality to me; the sight edges and surfaces are straight, sharp, and even, and the tritium circle and white ring outlines are crisp and precise. I do not have enough experience with other tritium front sights to compare brightness, but it certainly seems bright enough in lighting conditions dim enough to even need tritium. I was pleased that OP sent me the newest possible tritium sight - stamped "15".

There is a slight amount of slop in the fit into the slide, but that's probably normal for all front sights....so if you want it perfectly square, it may take a little extra patience as you counter the screw tightening effect on the final turn. The screw it comes with is surprisingly short, and almost seems insufficient, but it seems to do its job, and I was also surprised at how much I could torque on it for tightness. I applied some thread lock to the whole area. Use 3/16 Glock front sight tool.

I'm not sure there are many other tritium front sights as thin as .125 out there, in various height options, so this line of sights is a great option. I definitely recommend.
