The 7.65 Browning caliber is one of the most widely used cartridges for pistols worldwide, although the caliber 9 mm para is gaining greater popularity. It is the weakest ammunition suitable for service weapons and is particularly well-suited for weapons with unlocked mass locks. This allows for a lightweight design of the weapons, which is why firearms in this caliber are often designed as "pocket pistols".
The legendary pistol Walther PPK is manufactured in the standard version in the caliber 7.65 mm Browning (but is also available in other calibers).
Pistols in the 7.65 mm Browning caliber are generally lightweight, slim, and pleasant to shoot. A disadvantage of the caliber: the stopping power leaves much to be desired, and for hunting, the caliber is only recommended for roe deer at most.
