L-Roy,
Short of purchasing custom stocks, you might try what has worked for my wife if you have small hands. With the following setup she can shoot even the old "long" action S&W 45 frame revolvers in D.A. mode well. This won't be too comfy with a 44 Mag, or a "warmly loaded" 45 Colt, but it does work well for 44 Specials and 45 ACP/AR's. (The "Magna Grip" was introduced in '37 because of the recoil of the 357 Mag)
Try factory standard stocks produced before 1937, plus a grip adapter (an old Pachmyer, a Tyler, or even a factory adapter). Grip adapters come in different sizes. Find one that fits you. Use a shooting glove. Check the stocks on your N-Frame before you purchase them. All stocks produced prior to WWI and some produced thereafter were fitted to individual frames, some will fit current production revolvers much better than others.
