Description: This grenade consists of a fragmentation-type body similar to the Hand Grenade Mk IIA1 assembled to a fuze and stabilizer assembly similar to that for the anti-tank and practice rifle grenades. The stabilizer and fuze assembly threads into the gre-nade body.

The fuze is a simple impact type. The striker is held from the detonator by a safety pin and a creep spring. The safety pin projects through the fuze body and clamps around the stabilizer tube. When the pin is withdrawn, a drop of two feet, nose-first, to a hard surface will cause the fuze to explode the grenade. Detonation will not occur upon im-pact with water, mud, or soft sand. This grenade is designed primiarly for use against personnel.

Operation: The grenade must be placed on the launcher before the safety pin is withdrawn. The safety pin is removed before firing. When the grenade is fired, set-back holds the striker away from the detonator. On impact, the striker overcomes the creep spring and hits the detonator.

Remarks: The Fragmentation Grenade M17 is no longer in production; however, large quanties were issued.
