Factory UM's, they even look good ......for rubber. 

Maybe I need to re-think this. I have tried the UM boot grips a couple of times, but I had a hard time getting used to my little finger hanging off the bottom. I went back to the original banana shaped grip that came on my model 60-9 and 60-10. They do however conceal well. My hands are just medium sized. Do you that use the boot grip find that you do get used to the diminutive size with use? If I could get used to the feel, maybe I will take another look at them. wyatte
