M69 Practice Hand Grenade

HAND GRENADE GRIPPING PROCEDURES

The importance of properly gripping the hand grenade cannot be overemphasized. Soldiers must understand that a grenade not held properly is difficult to arm. Sustainment training is the key to maintaining grip efficiency. Holding the grenade in the throwing hand with the safety lever placed between the first and second joints of the thumb provides safety and throwing efficiency. Gripping procedures differ slightly for right- and left-handed Soldiers. Remember acquire target hold the spoon, pull safety clip off, pull pin, then throw!

Right-handed SoldiersRight-handed Soldiers hold the grenade upright with the pull ring away from thepalm of the throwing hand so that the pull ring can be easily removed by the index ormiddle finger of the free hand (Figure 3-3).

Left-handed SoldiersLeft-handed Soldiers invert the grenade with the fingers and thumb of thethrowing hand positioned in the same manner as by right-handed personnel (Figure 3-4).
