I think I have finally figured out what is happening. Yes the trigger pull is VERY long, then it tightens up right at trigger rollover. My finger at that point is very tight, pulling real hard, makes the skin tight. The trigger becomes so close to the frame, the tight finger skin actually wraps around the trigger, so tight the finger, wrapping around the trigger, bottoms out on the frame.
Either S&W will correct this problem, or I will have a gun for sale. My gun dealer has sold 4, and has complaints on all 4.
Dang... low serial numbers
