"High hand, crush grip, smooth roll of the trigger." Once you start the trigger moving, don't stop or "stage" it. Trust your "wobble zone!" Most students have a problem seeing the front sight properly. It needs to sit way down in the rear notch to keep from shooting high. There is a reason that most of the Pro Arms crew have Crimson Trace laser grips on our J frames. The guns are accurate, but the iron sights are a PITA! I've often wondered why, in all these years, S&W hasn't fixed that...on the basic gun, I mean, not on the custom and PC models.
I agree about the CT laser sight. The best shots I've had with my J-frame were with the LG-405. I regret I sold the laser set.
