Last week, I had a set of yellow Trijicon HD sights installed on my G19. My eyes, along with the rest of me, just celebrated their 42nd birthday. My eye sight is to the point, where I now need reading glasses.
To help my eyes out, I wanted a front sight that really popped. I strongly considered the Truglo sights, but decided to go with Trijicon.
Anyway, today was the first time that I was able to shoot with the new sights. The first few shots were way off, but I very quickly began to get the feel for how the new sight picture ought to look.
The Trijicon HD sights are three dot like my old ones, but instead of seeing all three at once, my eyes went immediately to the bright yellow front sight. What really threw me was the rear sights weren't easy to pick up. At first glance, it looked like my rears where solid black. I believe this is by design to further get your eyes to see the front post.
I put 35 rounds into the center of the target shown below at 50 ft.
There are men and women at my range who could do this and better all day long. However, for me this is a marked improvement. I just put that big yellow dot where I wanted and that's where the bullets went.
If you are considering new sights, check out the Trijicon HDs.
