The lights are designed to be hardened against recoil, so shooting your XD with the light mounted should be ok. But everything wears out. The more you shoot with the light on, the more use it is getting and that will accelerate wear to some degree.dtjobrien said:Just got my XML light for my XD-40 SC. I'm wondering if you guys practice with the light mounted, or do you keep it off?
Can a lot of shooting shock the light too much and wreck it?
