So these "people" think that your gun should never be used in a lethal manner, and that you should have no idea where your rounds are going?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".
Have they been listening to Joe Biden or something?
If you want the laser, get it. If it helps you, great!
Though I sometimes wonder about the "deterrence" thing that a lot of people talk about with regard to lasers. It may well be valid, but to me it smacks of the "rack your pump shotgun to scare the burglar away" stories...
