While the .327 geels less "snappy" than the .32H&RMag, and feels like it has less recoil (by quite a bit) than the .357 in both 2" and 4" barrels, there is little difference in sound indoors or outdoors between .327 and .357. All this is subjective data from one person.
On paper and in gelatin terminal ballistics between the .327 and .357 seem to be close enough not to matter. I certainly wouylds not want to try and catch either one.
.327 and .38spl+p feel about the same. Vanilla .38spl is, compared to .327, almost wimpy. Almpst.
Why are you looking to get away from either tried-and-true round that is given to those we think can't handle "real" calibers? And have you tried SWMBO out on .45acp? Many, even frail, women, find it a teddybear.
stay safe.
