Perhaps the most famous Walther pistol of all time is the PPK. Primarily made for the .32 ACP and .380 ACP calibers, the PPK is a more compact version of the Walther PP, which itself is a highly influential pistol. The PPK also became famous for being the standard issue sidearm of 007 in the .32 ACP configuration. The PPK was one of the most common concealed carry semi-automatic pistols for many decades, but has since become supplanted in popularity by many other carry options that are smaller, lighter, and more powerful. Nonetheless, there’s no denying that the PPK holds a very important part in Walther firearms history.
