The M1917 bayonet was designed to be used with the US M1917 Enfield.30 caliber rifle, as well as with the seven different U.S. trench shotguns. The blade was 17 inches long. It will not fit the M1903.30 caliber or the M1.30 caliber US service rifles as they have different bayonet ring and attachment stud dimensions.
History
The M1917 bayonet was used first during World War I by American soldiers on the Western Front. A sword bayonet design, the M1917 bayonet design was based on the British Pattern 1913 bayonet, itself derived from the Pattern 1907 bayonet, which incorporated a long 17-inch blade. While designed primarily for the M1917 rifle, the bayonet was fitted for use on all the "trench" shotguns at the time. Note that the M1917 bayonet and the British Pattern 14 bayonet from which it was derived were not interchangeable, and the two transverse cuts on the M1917 grips were meant to provide easy recognition in the dark. The M1917 was used frequently during the several different Banana Wars. The U.S. continued to use the World War I-made M1917 bayonets during World War II because of large stockpiles left over. The new Trench Guns being procured and issued were still designed to use the old M1917 bayonet. The bayonet was again called on during the Korean War for issue with the various Trench guns still in service. In a strange twist of fate, in 1966 procurement orders were let for brand new production M1917 bayonets. The contracts were issued to General Cutlery of Fremont, Ohio and Canadian Arsenals Ltd., the old Long Branch Arsenal of Quebec, Canada. Stockpiles had finally run out, and new Winchester 1200 trench shotguns were being issued. These were used in limited quantities during the Vietnam War. It was not until towards the end of the Vietnam war that new Military shotguns were designed to use the newer knife bayonets. Such as the Stevens Model 77E with the M5 Bayonet, or the United States Marine Corps"Model 870 Mark 1" shotgun with the M7 bayonet. M1917 bayonets were still in used by the US Army as late as the early 2000s for use with the M1200 shotgun.
