There are lies, damnable lies, and then there are statistics. According to those numbers a .32 is almost twice as likely to get a one shot incapacitation than a .40 S&W.
I'm not saying that .22s can't kill people. There was a pawn shop employee down the road from me who was killed by a negligent discharge. It got him in the heart and he was DOA. But that was from a 20'' barrel.
On the other side of that, there was a carjacker who took five rounds square in the chest from a .22 lr pistol with a 3-4'' barrel. Not one of the rounds penetrated deep enough to get to his heart or lungs. That should never happen. He then beat the car owner nearly to death, drove the stolen car out of state, and showed up in an ER hours later just because he was in pain. It's no exaggeration in this case to say that shooting him with the .22 served only to royally piss him off, and the car owner accomplished nothing but to get himself a beating he otherwise would not have received.
From a two inch barrel there's just not enough velocity to get through the sternum and penetrate to the CNS reliably. The bullet is also highly likely to be deflected or stopped entirely by bone. Even if you shoot someone directly in the head there are no guarantees. If the bullet is coming in at an angle it's likely to glance off.
It's your party, but I can't comprehend it. I don't think anyone would disagree that a P32 with a clipdraw is more concealable than a Bobcat.
