I just got my first set of Crimson Trace laser grips for a new Ruger LCP. To tell the truth I did it more on a lark than any desire or necessity but I thought "Oh, what the heck. It will be fun"! I learned a lot. First, you don't get rid of your regular sights and you still need to practice with them. Second, when I finaly got the CT sights "dialed in" I was simpy amazed at the kind of accuracy I could achieve! Third, I am impressed at how easy they are to install, sight in, and become competent with in such a short amount of time. I followed the directions and, Presto - the were up and running. Fourth, and finally, I am posessed of a pair of really "aging eyes" and that has become a problem - particularly in low light situations. The CT sights have really helped that situation a lot. So, for me, the laser sight experiences have all been a win, win, win situation.
