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.

That's a discussion on various sights and photos of those sights, this is a post about a review.  Two different things.

If a mod wants it moved it will be.

+1 for these sights.

I love mine on my 43. I want to switch all my sights to these but $$$

Awesome review, about 6 years late though?

Excellent review. Trijicon HD's are my night sights of choice.

.144 Width front

I do want to get my hands on some XRs now that they got that right.

I thought they release a new set that tamed or dehorned the sights.

+1

I really like the XR (thin front sight) version. It would be nice if Trijicon would sell the front sight only. I would really like a shorter front sight on my g19 to raise the groups up slightly.

Overall I really like these sights
