The felt recoil in revolvers, Magnum or otherwise can vary quite a bit. There is no recoil spring assembly in them like automatic pistols have. So, the size, or mass of the revolver has quite a bit to do with what you feel in the recoil force. The lowest Bullet grain wts. with modest velocities produce the least recoil. And at the other end, the largest grain wt bullets, with the maximum velocities produce the most felt recoil. In essence, a .38 Special +P with a 158 grain bullet, might produce more recoil than a .357 medium load with a 115 grain bullet.
I don't want to confuse you with all this, you'll catch on as soon as you start shooting it. The recoil thing is subjective of course, my wife went to steel shoots with me for a couple of years, she watched us shooting the biggest Magnums we could find. So when I handed her the .357, and she shot it, her impression was "No Big Deal", and she loves it. In the head kind of thing.
