Jack:
That is a very informative article by a very knowledgeable author.
With all of the on-going debates about this caliber and that, and that bullet weight and this, it is easy to forget that in the early and mid-20th century, many European police and military units were issued and successfully employed handguns chambered for the .32 ACP (7.65×17mm Browning) cartridge. Although I tend to follow the "bigger rock" school of thought, I believe even more firmly in the concept of "placement, placement, placement."
Thank you for posting that article.
