Description
The Trijicon HD GL101Y for the Glock pistol are a three dot tritium night sight, yellow front post accent design. The rear is U-notched and serrated. These sights have a .144 inch front sight width and .215 visible blade height. The rear U-notch is .169 and the rear visible blade height is .231, the HD's come in two front sight colors red and yellow. I chose yellow because I prefer yellow/green to red for catching my eye. I purchased the HD's when they were first released in 2011 for retail price, which I think was $150 at my local gun shop. They have not really come down in price anywhere and are available for $141.00 on Amazon. I have carried these HD's on my EDC G19 for about five and a half years, jumping from two different G19's (Gen4 to Gen3). I have fired over 50k rounds through both pistols with the HD's installed on them.
