I am about to order a stock for a T3 sporter, but I am not sure which model to choose.

I have used the Sako Classic before on a Howa, but found the grip to be to smal for me. No room for pinky finger on grip.

Does anybody know if the Sako Hunter or Hunters EDGE, have larger grips then the Classic?

Yes the Sako Hunter has a larger, more vertical grip with palm swell. The Hunters Edge and Classic stock grips are pretty much the same.

The sako hunter style stocks are sweet...

You will enjoy the Sako Hunter on a Tikka T3
