Homer, I run Aimpoints and believe them to be superior to other reflex type sights. One problem I have read about with the Trijacon sight you have is the dot/screen can be washed out when looking anywhere near the sun. Just what I have heard.

Do not think of a red dot as a short range only type sight, not that you would use a 45LC for long range shooting, but if you can see your target and know your hold over they work out far. This is where Aimpoint have an advantage in they are parallax free. I have shoot game out to 250mts and targets at 500mts using Aimpoints. So what ever range you want to shoot to with your Trijacon, go for it. As you can see by your target they are accurate.
