I think OHO is correct. I wouldn't mess with the stock unless you go through the motion to fit it to a specific person. Then you can decide which options to exercise. You can get recoil pads as thin as 1/2" and also could just put on a buttplate, if you need to shorten the LOP. Big heavy orange pads are not my favorite.

What you do to the rear end of the stock will also bear on the balance of the gun, so choose wisely.

Have the chambers measured and you might find the recoil lessens if you have 2-1/2" chambers and use the right ammo...I wouldn't be surprised if the chamber length is marked on the barrel flats.
