Re: Pistolgrip or regular stock?
What type of grip is on your existing stock?
Do you like it or do you want to change it?
Personally, I do not pistol grips on a rifle, but it is your rifle.
If you like your existing stock, why not just modify the comb and LOP? That would be a lot less money than buying a new stock; that is what I do. Custom fit is far better than adjustable.
