The Krav Maga training hand grenade is made of moulded rubber. It is based on the 'pineapple' type hand grenade. It weighs a little over the true weight (at 615g). The pin is removable but all other parts of the training aide are a solid, one part mould. Perfect for practicing grenade disarms or for training props. No sharp edges. WARNING: This item may look realistic from a distance. Please train responsibly.
