Lazers on any gun is just a sight- like it or not- that's what it's for. They are very good and just for the people that don't know or care, it will make you a better shooter. No matter what lever you are it WILL jump you up a notch or two right a way. Some people are just too cheap to put one on a pistol or revolver. ( They seem to be the ones that bad mouth them all the time.) Use it and it will help you. The only time it is not a help is at high noon during the summer, too much sun light for it.
Have a nice day ya all.
