If you can locate a copy of Chic Gaylord's, "Handgunner's Guide" published about 1960, look at what he had to say about the experience of a NYC detective who shot a felon in the head with a .32 Long. Also look at the photos of gunshot wounds to human bodies in the book. Some are head wounds.
There is good reason why most cops still carrying .32's by the 1950's were policewomen, who seldom had to fire their weapons. The same was true of Euro cops carrying .32 autos.
I think that member Old Flatfoot may have some reprints of the book. He knew the late author and was inspired by his holster business. Look in the Vendor area and PM him and ask if he can sell you the book. And, considering that he is also a retired NYC detective, ask hm what he thinks of the .32 as a police weapon.
I think that Geco and others still make a full wadcutter round in .32 Long. It might add a little stopping power to this weak CTG. You can carry a J-frame .38 Special about the same size and weight and have a much more effective defense item.
In Peter O'Donnell's superb novels about Modesty Blaise, she used a Colt .32 a lot in the earlier books, but placed her shots better than anyone but maybe a trick shooter in a circus can. And even Modesty used a .41 Magnum or a Star PD .45 when she could. I'm quite sure that the sole reason why she didn't wear a small .38 was the writer's wish to give her a gun that seemed to suit a girl.
I think you can kill most snakes okay with a .32 and they'll knock over a rabbit with flatnosed bullets, but I wouldn't want to have to shoot anything larger than a jackrabbit with one.
When I wrote a series of stories featuring three women in the 1920's who needed handguns, I deliberately had them carry S&W M&P .38's. Sometimes, they had to shoot very bad guys, and I didn't think they could do that as well with .32's, especially at any extended range.
I know that .32's are small and cute, but wouldn't count on one to save my hide, especially if an opponent was drunk or on drugs or highly adrenalized. Of course, if you can shoot like Modesty Blaise, you can just put a bullet through his eye into the brain and probably come out alright. Alas, that tends to work better in fiction than in real life.
