I have Spegel Boot grips on my Taurus 85CH and had to do so reshaping with a Dremel to relieve the grip enough that the right hand panel would fit flush on the frame. Only took about 15 minutes, but be aware that this sight doesn't just "screw into place". I tried the stock grips and they didn't fit either.
Pros: Light weight, bright laser and good price
Cons: The grips have to be relieved for good fit
