Experts say noone uses sights when firing under stress so this should allow you to instinctively point shoot and hit the target more often.
Pros: Easy to install and did not require much hardly any adjustment to be right on target. Nice bright , large laser dot to get the attention of your target which may be all you need to resolve a situation. Allows you to have free hand to hold a flashlight, open doors, etc and still know exactly where your gun is pointed.
Cons: Cost.
