The M17 (also known as the T2 grenade[2] ) is a rifle grenade used by the United States during World War II.


The M17 consists of two major parts, the warhead and the launch adapter. The warhead is a Mk 2 grenade's body, while the adapter has an impact fuse at the end of it. The warhead can be easily screwed into the adapter.[2]


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.

Note that the M17 will not explode if it lands on sand, water or mud; only solid ground will cause it to detonate.[2]



The M17 was adopted in 1941. It was the United States' primary anti-personnel rifle grenade during the early parts of World War II.[3]


By the middle of 1944, the M17 had been declared obsolete. It was replaced by the M1 Grenade Projection Adapter.[3]
