I have them on three handguns, a T-series 9mm Browning Hi Power, an S&W 637 J-frame snubby (the first to get them), and an S&W 686. Crimson Trace laser grips are a must for me, so much so that I will not buy a handgun that CT does not make a set of grips for. Of course, I'm eighty now and cannot even SEE the iron sights without my glasses on. But in a home defense situation and Crimson Trace laser grips, I'm good enough. I belong to a range and usually practice weekly at 5-10 yards.
For those who feel no need for laser sights or feel they are too expensive, I have no quarrel. However for those who sneer at laser sights, I have a question: Did you try them once in front of friends, and were humiliated by the way the red dot staggered all over the place? If so, that was you, not the laser. But then, deep down inside, you knew that.
Cordially, Jack
