I was given a used racquet - about 8 years old now. The length, size, weight of the racquet I like, but the grip is too big. I do not know if this is possible, but the butt cap is labeled P5 (Prince), does this mean it is 5"? Huge grip? Is there anyway I can get this reduced? Can I just sand down grip to a size I like and apply a coating to protect the wood or get it professionally done? Thanks!
