Interesting how many small and underpowered cartridges have been used over the years. Anything from 22 caliber and 30 caliber through 32 and 38 short.
Many of these were the favored tools of assassins and in some cases, the military. Many more for self defense.
Certainly these cartridges are, for the most part, obsolete and have been replaced by more powerful rounds, but they were still capable of taking life.
You can't disrespect an old weak(by today's standards) cartridge because it can still kill.
Just as knives and spears, bows and arrows are still capable weapons in the right hands.
