My old Bushnell Phantom was 1.3x, more than enough. 2x is about as high as you can go unless you're unhumanly steady. The real issue is eye relief, and the need for a pistol specific scope. My experience was with an old semi-auto and then with a 617. Its interesting, but without a good rest it sure seems to make your shakes look awful. Consider buying the scope used if you can find it. You've got less invested that way, and there's a very good chance you won't like the end product.
