The Walther PP and PPK were designed around the .32 cartridge. The .380 was never considered a good choice, even by Walther, until it was forced on them by GCA 68 (more points) and then by the idea that a .32 was a harmless toy that could never harm anyone. I have not bought a new .32, but I just might.

P.S. (I once carried a .32 S&W HE, and when derided by another deputy about the tiny little bullets, I suggested he stand there while I put a "tiny" bullet in his eyeball. He chose not to accept the offer.)
