My second choice behind a Walther PP is the Beretta Model 81 (bottom).



On the plus side it’s a 12 + 1 round double stack .32 ACP pistol, it has a better DA trigger than the PP, and the open slide design is extremely reliable.

On the negative side it is large for a .32 ACP pistol which can work against the reason you might want to carry a .32 ACP pistol in the first place.
