The M-1917 had a smaller explosive charge than earlier designs, as the power and quality of the explosives had improved. The grenade also incorporated a flanged screw off cap on the bottom of the handle, which secured the detonating pull cord, and reduced the chance for accidental arming of the grenade. A cylindrical ceramic weight was also added to the bottom of the cord. This weight made it easier to remove the cord from the cavity and to pull the cord. The wooden handles were stamped with the fuse time and the date of manufacture of the grenade. The explosive head of the grenade incorporated a belt hook, to allowed the grenade to be hung from a belt, or a fence as an improvised booby trap.
