Hi edison!
I presume a new purchase is not in order so: skate board tape, light dimpling with a center punch, use a small brush to apply some of the dip-type rubberized coating? Perhaps the best alternative is to try the finger-gooved model? 334Dave's rubber Bucky is a very good approach but may be some time off so a standard finger-grooved model is not that expensive to try. If you did want the ultimate 110 and grip-ablility, investigate the many options to choose from with a Custom Design Custom Shop 110! Stag, elk, grooved buffalo horn in addition to the finger grooves will keep that puppy in your paw all right!
