I have the larger of the two CT grips on my 3" SP101.I ccw this in the winter months when it is darker longer. It is carried in a OTW holster so the size of the grip is not an issue as it would be if I pocket carried. I have three other SP101's that do not have a CT on them but I have found that when swapping the CT from one revolver to another that zero is not affected much. hope this helps.
