I've done a good bit of shooting with big bore revolvers and what I've learned over the years is as follows:
First and foremost, at a certain point a gun can become simply too light to be enjoyable with full-power loads. I learned this the hard way with a S&W M21-4 .44 Special. I bought the gun with the intention of shooting Kieth .44 Special handloads in but when I got to the point of Kieth's powder charge with a 200gr bullet, the 37.5 oz weight of the gun was just too little to soak up the recoil adequately for me. The top-end loading that I could stand in that gun was the Skelton load which ran a 245gr bullet at 900-1000fps. The lightest gun that I can put up with the recoil of a full .44 Magnum load through is my standard 4" 629 which weighs, according to S&W's website, 41.5 oz.
Secondly, it is imperative that you use stocks which fit your hands well. I can't really recommend a brand or style to you because I don't know the size and shape of your hands. I can tell you, however, that in my experience, the shape and size of the grip is much more important that the material from which it is made. What you want is a grip that is large enough to fill your hand but not so large as to make you take an awkward or uncomfortable grip. You don't want too small a grip because it will direct all the force of the recoil into a fairly small portion of your hand rather than distribute it throughout your hand. However, too large a grip will force you to grasp the gun in such a way that the force of recoil is directed into your thumb and/or the web of your hand rather than the palm where it should be.
Right now, my 629 wears a set of Hogue X-Frame grips and these are the most comfortable that I've tried because they fill my hand and have a soft cushioned area over the backstrap. That being said, both rubber and wood Hogues with open backstraps work nearly as well for me because they still fit my hands well. My M57 .41 Magnum currently wears Culina Magnum Profile Targets that, while not quite as comfortable as the Hogues, also fit my hands well and are not unpleasant to shoot with. That being said, I have large hands (I wear XL gloves) and long fingers and what fits me well may not fit you.
Finally, the technique required to shoot a bigbore magnum comfortably is quite different than that used to shoot a semi-automatic or smaller caliber revolver. With a semi-auto or revolver up to .357 Magnum, I find it best to grip the gun tightly and "muscle down" the recoil by trying to prevent the gun from moving as much as possible. With a .41 Magnum and up, however, this isn't really the best thing to do for an extended shooting session. While I can "muscle down" a bigbore (you really have to for fast DA shooting), doing so becomes very tiring and uncomfortable after two or three cylinders full. For a more extended shooting session, you really need to "roll" with the recoil rather than fight it.
What I mean by that is that while you should still grip the gun tightly enough to hang on to it, you don't necessarily want it to move as little as possible. Allow your arms to move at the elbows so that the gun can rise a fair amount under recoil. If done properly, you won't notice any degradation to your accuracy and the felt recoil will be much less unpleasant. Using this technique with a gun that is heavy enough and fits my hands well, I can go through 50 rounds of .44 Magnum in one session without it becoming unpleasant.
