The pressures of the .327 Federal are higher than for the .357. I personally wouldn't chamber any handgun for that round that was originally chambered for a lesser .32 caliber round. You would think that any K frame made after model numbers were assigned to have sufficient heat treat, but that's a potentially very dangerous assumption.
.32 H&R on the other hand might well be possible and safe if the K frame had a model number assigned.
