Grips will also vary grip to grip, so try before you buy! A lot of people really get on with Rink Grips, or Ciro, or Minelli or whatever..... to get any grip 'perfect' you will have to work on it yourself, you will need to add putty or remove wood or more likely both! My advice would be to find a grip that fits you pretty well and then be willing to work on it. Size guides are available online, also consider speaking to the dealers (Harry at Steyr, Iqbal at Morini, Paul at Pardini etc) to get advice and to try grips out. Grips are very important to shooting well so don't rush into anything!!
