Nill makes a nice selection of N-frame stocks. You can probably find a design that would help your shooting. The gun should not feel like it wants to move around in your hand.

Nill stocks are not inexpensive, but the quality of workmanship is excellent. If you see a model you like with checkering, you can usually special-order it without checkering. Smooth stocks are usually considered a plus on a 44 Magnum (particularly on a 4-inch gun), as you can see on Doc44's revolver.
