I would disagree with the 32 acp, I understand it is not popular in the US but at one time I did a tour and was issued with a 32 acp Walther PP and was quite happy with it. I didn't obviously have a choice I got issued with it.....
Now without going into the whys and wherefores I was present in a pub with three colleagues after work one evening having a quiet drink when three masked men burst in.
They almost immediately identified members of the group as police, the closest bastard fires two rounds from a GP35 at the nearest officer (who was 6 months to retirement and our officeman), as he went down but was able to draw his Walther and shot the assailant, and from the floor put the second man down. By now the pub is in uproar as it was packed.
Notwithstanding he made a good shot from the floor, and in great pain at the third man, who was making for the door, hit him square in the back. He crashed through the door and into the street (we later believed he was dragged into a waiting taxi).
I am not posting this as a bit of daring do to impress anyone, because those of you who have experienced these incidents understand it's sometimes difficult to recount, although retired cops are the worst for war stories.
The point of this being I have a grudging respect for the 32 acp when carried in a quality firearm, and in my view far superior to the 380 (low recoil, additional round, accurancy, penetration etc.).........
During the unpleasentness I was at the far end of the bar I got into cover had no opportunity to assist. But I didn't spill me pint!
Oh yes, the police officer man a good recovery and made retirement, still lives where he served, and if still with us no doubt bouncing his grandchildren on his knee.......
