I use 3M tape and buy it off a i inch roll at Ace Hardware. Lately, I have been using the 3M "pebble grip" tape and like it. If it is too rough for you just lightly sand it with sandpaper to soften it. It is cut to fit on my grips, front and back strap, and even a small piece on the mag release and grip extension to avoid slippage. The bar code for the pebble grip tape is #51131 5906. It comes in gray but they make other surface material in black, also.
