M1917 bayonet

The M1917 bayonet was designed to be used with the US M1917 Enfield .30 caliber rifle, as well as seven different models of U.S. trench shotguns.

While designed primarily for the M1917 rifle, the bayonet was fitted for use on all the "trench" shotguns at the time.

US surcharged P1914 bayonets exist and will exhibit the British proofs being cancelled out and US marks applied.

The bayonet was again called on during the Korean War for issue with the various trench guns still in service.

It was not until towards the end of the Vietnam War that new military shotguns were designed to use the newer knife bayonets.
