Not necessarily. There are a number of rounds marketed as .32 Caliber or 7.65. .32 Automatic Colt Pistol, .32 Auto, 7.65x17SR, 7.65 Browning, and 7.65 Browning SR refer to the same cartridge. They are not compatible with other .32/7.65mm cartridges such as the .32 Long Colt, .32 NAA, and others.
The 32 ACP or 32 Auto is known as 7.65 Browning in Europe.

No.
What kind of shells do you use for a 32 cal 32.auto
Pretty much the same as any other revolver or semi-auto.
Nothing.
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.
.32 caliber is not enough infromation. Ammunition marked "7.65 Browning", ".32 auto" and ".32 ACP" for practical purposes, are all the same. Do NOT try to use ammo such as ".32 magnum" or ".32 long" as it would be a different round.
