Truglo are good sights as well as Trijicon. However I prefer the Richard Heinie Figure 8 Tritium Sights on my Glock 22, Due to the fact the human eye can line up vertical configurations much quicker and more accurately than horizontal alignment. You simple put the front sight dot on top of the rear sight dot and shoot. With the three dot system as you know you have to line up the front sight dot in the center of the rear two dots and also have the correct space side to side and also elevation! Just a though you might want to take a look at. Personal preference also is involved so good luck in your choice. "Happy Shooting!
