Got these for my Sig P226 and they work great. I really love the contrasting colors for low light and dark situations. I will recommend that a gunsmith install them. My gunsmith installed them on my Sig and broke the front sight. This was not a defect or Trijicon's fault, this was my gunsmith's fault because he didn't follow the instructions in the package that says to only use a Sig install tool. This is because the P226 slide it tapered in the front and a normal install tool will not press the front sight perpendicular to the slide.
Pros: Great visibility - day, low light, and night
Cons: None
