I have CT grips on my carry revolver because the iron sights can be quite difficult to see in low light.

If aiming in daylight or well lighted areas, the laser will be useless because you can't see it. No switch necessary, there is a power switch but I leave it on all the time, the switch that turns the laser on is on the grip, just grab the weapon normally and the laser is turned on.

I also find the laser to be a good tool for practicing trigger pull during dry fire practice. about 7 yards away while dry firing, you can see the laser move if you mess up the trigger pull even a little.
