The Mauser C96 (Construktion 96) is a German self-loading handgun. It was one of the earliest self-loading handguns developed, and the earliest truly successful one, being adopted by many national militaries and remaining in service for over a half a century. The original weapon was chambered in 7.63x25mm Mauser, and fed from a 10-round integral magazine set slightly ahead of the pistol grip. It made use of a short-recoil system of operation.
Many variants and rechamberings of the weapon were developed, including 9x19mm and .45ACP versions, cavalry variants with extended barrels, carbine variants with handguards and shoulder stocks, variants fed from extended magazines or detachable magazines, and even a fully-automatic variant.
A close relative to the C96 Carbine, the M1917 Trench Carbine, was designed to fulfill the need for a trench-raiding weapon for German storm troops. However, due to it not being fully-automatic and the fear that its production may interfere with that of other weapons, it was never mass-produced. However, German officials still found the 40 round magazine impressive.
