.32 caliber
The Walther PP uses a variety of ammo, depending on what model you own. The most common type of round used overall is the 7.65mm round and the majority of Walther PPs and PPKs were designed around this round. There is also the 9mm Kurz round that could be used in these guns also. It was only after WWII was over that the Walther PP and PPK were redesigned to shoot a .22LR round, but production lines were shut down soon after because the .22LR was not a common round at the time, so few were made in relation to the standard 7.65mm. The least common type of round used by Walther PP series was the 6.35mm round, which the PP and PPK were both originally designed to use early in the war.
The Walther PP was made in 5 different calibers- ONE of which was .32 Auto. If the gun is question is a .32, it can shoot .32 auto. If another caliber- no.

Only if it is the same type. There are different types of 9mm and they do not interchange as a rule. For example, the Walther PP fires a .380 ACP round, known as 9mm Kurz. This cartridge is shorter and not as powerful as the 9mm Parabellum, also called 9mm Luger.
