Can I shoot 380acp caliber out of my 32 pistol?
No.
Absolutely not. IMPROVING ANSWER: It won't even fit, although you can't tell the right ammo to use in a gun by trying it to see if it fits. A .32 caliber gun fires a bullet that is about 32/100 of an inch wide. A .38 special handgun uses bullets that are about 36/100 inch. So the bigger bullets will not fit through the smaller holes in the chamber and barrel on the smaller-caliber gun.
Bullets are not likely to do you any good. You can not reload rimfire ammunition. You need to search for loaded ammunition.
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.
