I just applied stick on grip tape to my pup. It is 3M CLEAR which I not only applied to front and rear straps, but also on the flat surface part of the grip itself. It is almost invisible on the straps, but looks like dried silicone rubber over the grip surface. However, it comes off easily without residue. It is NOT abrasive/sandpaper variety. It does produce a firmer hold. I will report back after going to the range. I procured one foot of 4" wide for 2 dollars, so I may try it without the pieces on the grips as well. the rear lower grip screws are covered, but access would be easy by just peeling back very little. When I get time to set up posting photos, I will share this project as well. BTW, I obtained from my local BOW(Boat Owners Warehouse) store. Larry
