I am going to pick up an S&W model 37 airweight this weekend. It comes with uncle mikes boot grips and I was thinking that I might like to add laser grips to this gun as it may go to my daughter. There seem to be some very good deals on the CT 105 models for this gun with the 305's and 405's being quite a bit more expensive. The 105's come with the full 3 year warranty so I am wondering idf there is something wrong with them. The only difference that I can see is the size and shape of the grip. It appears to operate the same way as the other models. Do any of you have any experience with these? Even if you have a different model, how do you like thema and, are they worth the price. I recently picked up a S&W 1911 with laser grips on it and really liked it. I am thinking this would be a good move for a small revolver with very basic sights.
