Browning himself was not done with 35 caliber cartridges and would soon introduce the 9mmBrowningLong in 1903 and the.380 ACP in 1908.
The.38 Super offers higher bullet velocities than the 9mm Luger, and it is better suited for hot-rodding as it has a longer casing which allows for larger powder charges.
Due to Mexican laws which have restricted the civilian use or possession of ammunition classified as "military caliber," such as 9mm, this is a popular round in Mexico.
The.380 ACP (Automatic Colt Pistol) pistol cartridge is a rimless, straight-walled pistol cartridge developed by firearms designer John Browning.
It was introduced in 1908 by Colt, and has been a popular self-defense cartidge since then, and is most famously associated with the Walther PPK, better known as James Bond's handgun.
The.380 ACP (also referred to as the "9mm short" or "9mm kurz", German for short) is compact and light, but short ranged and having marginal stopping power.
