Vise makes a sleeve they use for vacu-grips and you can get the finger slugs. They are like thumb slugs, but smaller and re-drill them to the 31/32 size. The larger grips as stated are 1-1/32. I have glued thin plastic strips into the holes instead of tape to tighten up the grips. Lots of options without replugging, but plugging may be easier. Just my $.02, Bruce
