I recently broke the bank and went for a 629 Competitor. It's fun to shoot, but the butt does kick back into the web of the hand with some force. I don't want to risk nerve damage over time. I could use a glove. But I'm also considering replacing the standard grips with S&W 500 Impact Absorbing Grips. In reply to my email, S&W indicates that those grips will fit the 629 Competitor. However, when I look online, the model 629 is not among the list of models compatible with those grips. I was wondering if anyone out there has tried them. Also, has anyone had experience to say whether the S&W 500 grips make a noticeable difference vis-a-vis the standard Hogue grips? Any information would be much appreciated. Thanks.
