I have heard that laser sights on a hand gun are more show than go. My instructor said there is a rule of 3. Most defensive gun fights occur in less than 3 feet, 3 shots or less are fired and last about 3 seconds. I can see if your searching for an intruder in a darkened home it could give you that intimidation factor but the blinding light of a flashlight will give you more of an advantage. Anyone have any practical experience where a laser made a huge difference?
