I also would not consider .32 ACP in a modern J-frame S&W 30/31 as unsafe, but for any manner of defense I would wholeheartedly suggest that it is a -BAD- idea.
The .32 Auto case is semi-rimmed (like a .38 Super) and it will sit nicely in the cylinder but it will -NOT- play nicely with the ejector. You can almost count on at least one of the five empties being "missed" by the ejector and once that empty is nestled under that ejector, getting it out under even the mildest stress is irrationally difficult.
For range play, give it a shot... You'll likely notice very early in the session how prevalent the problem is.
Also, to be sure, regardless of what we think AND what we know, doing this ABSOLUTELY goes well outside the bounds of SAAMI. In these forums, that usually carries an "official" warning.
