Description
    
"GRENADE, RIFLE, FRAGMENTATION, IMPACT, Ml7—
This grenade consists of a fin stabilizer assembly with impact type fuze similar to that used for Grenade, AT, M9Al. The head consists of a Mk. IIA1 hand grenade fuze body which is screwed in the fuze adapter on the stabilizer assembly. The Ml7 grenade is used in a manner identical with that of the Adapter, Grenade Projection, Ml, however, it offers a unit ready for firing without assembly in the field as is required for the Ml adapter"

Firing
    
Once the warhead is screwed in, the M17 is fitted onto a grenade launcher adapter, such as the M7 grenade launcher. A special blank .30-06 cartridge is inserted into the rifle, then fired. The M17 will not explode if it lands on sand, water or mud; only solid ground will cause it to detonate.[2]
History
    
    Adoption
    
The M17 was adopted in 1943. It was the United States' primary anti-personnel rifle grenade during the middle part of World War II.[3]
Obsolescence
    
By the middle of 1944, the M17 had essentially been supplanted by the M1 Grenade Projection Adapter,[3] which allowed a standard grenade to be converted into a rifle grenade.
