JHPs
I carry Corbon 135s in .40 S&W in a 1911 compact. The Corbon has consistently had excellent ratings in one-shot stopping power. Very good expansion characteristics, and ideal penetration. These have been used by a number of police departments. It's been suggested that I switch to a .357 Sig, since that's what the Austin cops use.
JHPs are designed to stop, not kill. If you are only shooting to wound, then the question becomes, why were you using lethal force at all? A question you really don't want to hear the prosecutor asking you. All the police forces I know of tell you to shoot for center of mass. Hydrodynamic shock helps the stop by causing the perp to suffer sudden nervous system overload. An FMJ, on the other hand, overpenetrates, wasting huge amounts of energy. Why have all that muzzle energy if you're not going to use it?
.32s effective? Not really. They don't have the energy to do any effective damage. A 65 grain bullet going at 950 fpm just doesn't have any real penetrating power. If European police are actually using them, then they may find themselves seriously outgunned should a real criminal organization come along. Miami was the reason the FBI went from 9mm to 10mm and later the .40 S&W.
I've been shooting for over 40 years now, and competitively for 15.
