I want to put a pair of BUTLER CREEK rubber grips on a 4" mod.66. Any thoughts on what would be better for general handling and occasional carry would appreciated. I have a pair of BUTLER CREEK boot grips on a Mod. 60 and like them fine on that gun. Would the boot style be alittle too small for the K-frame or would there be enough grip to hold on to? Would the Combat style be better or too bulky? thanks,QUADCAB
