I am using it on my xdm 9mm. It works great, but dot is small and it is hard to see in day light.It appear to be due to the small green dot. I have a aimshot green laser and the dot is bigger and it is easier to see in the day light.
Pros: can see it very far, also fits my xdm 9mm 5.25
Cons: dot to small, makes it hard to see in day light
