Poor wood-to-metal fit plus too thin at the top, which pretty much applies to all stocks these days.
Those grips look really rough with the squared edges. Sanding them down flush to the metal and putting a radius on the edges will mitigate, if not eliminate the bite.
IMO, this started when speed loaders became prevalent. Stocks started getting thinner on the cylinder side for SL clearance. Add to that the decline of hand-fitting, and stocks started biting.
This is why all of my K-frame round-butt revolvers wear these Uncle Mikes grips. I can shoot magnums till my heart’s content. They’re discontinued, but available on EBay. They were designed by Craig Spegel and are very ergonomic l.
“Toughening up” doesn’t do much good. I have a permanent callous built on the web of my hand, right at the base of the thumb. One cylinder-full of .357s with the wrong grips will rip it right off.
As Malamute said, a set of factory football-targets (or earlier targets) work very well, but aren’t practical for concealment. Plus they’re too big for fast DA work with my stubby fingers. For their intended purpose, target shooting, they’re near perfect, IMO.
That looks like it’s designed for inletting more than external shaping.
A plain card scraper or one with a convex edge may work better:

I actually contacted Altamont about this when I first got it to the range, I asked them if they did any shaping or anything...their response was "no, it fit on the gun as it shipped but if you're not happy with it, you can send them back - we'll do a refund, no problem." (or words to that effect - they weren't snippy or giving attitude about it - it was more "that sucks! we're sorry, we can refund if you wish" in tone)
Right now I'm kind of looking at them in the frame of "The grips are %90 finished and it's up to the user to do the end finishing to fit their firearm"...if you look at them as "kit grips", I guess, they make a lot more sense. Expensive grips to be sure, but also pretty...
The left side could probably stand a little more shaping, but not too horrible for a first blush. The left side also needs to be cleaned up a bit more; I didn't get to all of the scratches with 400-600-2000 like I did the back edge and right side...
you did a better job than I did!
Oh, believe me - if you saw it in person, you'd be wondering why an ecliptic decided to set Youtube to a "Tokyo At Night" playlist before picking up some sandpaper.
That should feel much better now!
Pro tip; make a couple of small (say 1/2” x 1 1/2”) hardwood blocks you can use to double stick your paper on for the edges. You can do two sides of each block and then a second block for the finest grit. The beauty of these is that if one is too wide, you can narrow them easily for a particular task or area.
Working along with the grain, these sandpaper files will keep you from rounding corners and edges. On wood like that, I’d use 220 or 240 for final shaping, 280 next, then 320 to start removing scratches. Then 400 to 600 for scratch removal and polishing. 800 is optional but I wouldn’t go beyond that if you’re putting a finish on them.
