I have been considering getting the Viridian C5L for my S&W M&P .40c concealed carry gun. Mostly for deterrence and total effectiveness in any situation. I live in Maine which is a Castle Doctrine state and has a stand-your-ground law. But I have heard from a few people saying that it's not a good idea to have a laser due to the fact that "you know exactly where your round is going and if lethal forced is used it was intended for that reason". And in return could back fire in court. Any thoughts or personal experiences?
