I agree with ljnowell. Mine doesn't feel like either of the revolvers you asked about. It is, as he said, more similar to a .40 S&W or maybe a .38 +P in a large frame .357 revolver, not a snubby.
I generally have a 22 lb spring in mine, but depending on the loads, I also use anywhere from a 20 lb to 16 lb spring. The recoil spring makes a big difference in felt recoil.
