the .380 round was introduced in 1908 which was for use in the modified 1903 pocket pistol. The first European pistol to adopt was the Browning M1910, the type of pistol used to assasinate Archduke Franz Joseph and his wife Sophie. It became a very popular round and was used across a variety of pistols.
Now a hard to get round since there is no legal pistol shooting in the UK, hence the price, free from explosive, no licence required
