The .32 is not much loved these days, but was pretty popular among European police through most of the last century.
A Colt Pocket Hammerless from 1919. Just in time for Prohibition, might be found in the pockets of folks, from gangsters to general officers.
The Model 1922 Browning was FN's response to a request from the Yugoslavian military. Many were still in use by the Bahnpolizei in Germany well into the Seventies.
The PPK, from 1965, remembered mostly as James Bond's sidearm and a victim of the GCA '68.
1969 Walther PP, this one Bayerische Staatliche Polizei surplus when the Cold War Status of Forces Agreement allowed them to be sold dirt cheap in military rod and gun clubs.
In November of 1974 I was in the Frankfurt am Main Haupbahnhof. I don't why, but the Bahnpolizei were chasing some Turkish guy down the platform yelling for him to "Halt!" One of them ran out of patience and carried out his promise, " ...oder ich schieße!" He was apparently a pretty good shot. One round of .32 ACP from his M1922 at about 15 meters did the trick. I don't know the rest of the story. My train boarded before all the commotion was over and I missed seeing anything in the news.
