I was looking at lasers for my lcp and have seen commercials for this has anyone tried it yet
Using a laser you will focus on the laser beam, meaning you are focusing on your target.
You are making a habbit that will be hard to break.
Proper marksmanship and sight picture means focusing on your front sight.
So if marksmanship is not your goal and you just want something for self-defense, it may work for you.
