My preferred .32 is a Walther PP in .32 ACP.



The .32 ACP takes a bigger hit than even the .380 ACP in shorter barrels. However the 3.9” barrel of the PP is sufficient to launch a 60 gr XTP at 1000 fps. At that velocity it will expand nicely and penetrate about 13”. You also have 8 plus 1 rounds in the PP.





75 gr cast bullets are also popular as a self defense load but they will not expand regardless of velocity and over penetrate, 27” in this case.
