The pistol grip should ideally not be longer than is needed for 3 fingers. If you have a finger groove on the side of the action too (I see yours has but maybe made even more pronounced Tommy) to locate the trigger finger straight on the side of the stock providing grip and leverage for handling the rifle with the finger well away from the trigger while getting up and down then there never needs to be room for more than 3 fingers on the pistol grip, or maybe even 2! you know who you are!!
My Anni has that groove and the Ginb on my BSA did, it is a feature I like.
HFT, for people with only 2 buttucks!
