OK, I am posting this for a buddy who has several health issues, but loves shooting. He recently bought a new Taylors sharps, 1874 model that has the straight stock. He is in a wheel chair, among other things, and cant get the stock to sit where he wants it. He needs a pistol grip stock, will they even interchange, and where would a person get one. I told him the bottom tang would probably be need to be curved, and maybe the top one also, Anyone have any of the italian made sharps with a pistol grip stock, is the stock just contoured, or does he need to sell his rifle and get another one.
