When the Kingdom of Italy marched to war in 1915 they carried the black powder Bodeo revolver in their holsters. Over the course of the conflict development of a reliable autoloader would prove problematic until later in the war.

A crude Spanish copy of the Colt Model 1903 became the most common French handgun of the Great War, seeing extensive service in that conflict. Despite its almost disposable nature the pistol would remain in service for decades beyond as well.

The slightly larger forerunner to the famous Walther PPK, the Polizei Pistole was used by German police and military officers during the Second World War. Remaining in production until the capture of the Walther factory in May of 1945, several were captured by US troops at that time.
