The altamont grips I use are smooth super rosewood or smooth silver black. They fill the hand a tad better for ME, some people don't like them because they are smooth.
My RH's are of the 44mag & 45 colt variety. Using cowboy loads their is some felt recoil but nothing not bad. Using full power large game loads is diff, felt recoil is much stiffer, but still within one handed use if need be. To me the gun jumps and moves in my hand more with factory grips, the other day at the range I fired a friends rh in 44mag using buffalo bores hottest loads and I have to say I much prefer altamont, the let me get a much better grip.
I haven't found a spare pair of grips yet, but I've still got tons to go thru. Lol, I should set up a table at the next show. In my ammo bunker, I have every box on each weapon I own, along with its factory grips, and mags should it be a semi, and the are all vacuum seeled for preservation, the grips and mags seeled then seeled again in the box, going back some 40 years.
I don't normally sell anything gun related as you just never know, one of the concrete rooms in my bunker is devoted to holsters, parts, grips, and ammo for items I don't own or have owned and traded. When I was a dealer years ago, I picked up a large police sale on colt pythons, 4" nickel plated along with holsters, speed loaders and spair parts. Paid the department $425/gun and parts and bought 255 of those that officers didn't buy for themselves. Been sitting on them until recently where I sold them to a company at twice what I paid minus a few for myself, and the parts they purchased seperately. Police weapons are great, lotta wear but little use, and when you buy police dept lots, many are unissued. The pythons I kept were all the unissued ones.
I'll keep looking and let you know what I dig up.
