is an entirely inert (no explosive content) version of the L109. Identical in size, weight and shape, as the live grenade and is used for training purposes, specifically correct handling and throwing. It can be easily distinguished from the live grenade as it is dark blue with white markings (see below). The body is solid aluminium with a textured plastic coating made in the same form as the live grenade, the textured coating ensuring a good gripping surface. A hole drilled up from the bottom indicates an empty store as well as ensuring the drill grenade is of the same weight as a live grenade. A bushing on top of the grenade has a dummy fuze mechanism permanently attached with a slot for the pull ring to clip into to prevent it being accidentally pulled. The fuze mechanism, under the plastic cover is very similar in appearance to the American fuze mechanisms. Internally there is an extension on the striker to allow it to be re-cocked during training and there is a leaf spring safety that clips around the safety lever and neck of the grenade preventing the lever from rotating even if the safety pin is pulled. The markings are 'GREN HAND INERT DRILL L110A1' and a manufacturers marking "SM" meaning Swiss Munitions. The fuze mechanism is marked on the wide bottom portion of the lever "HG2 DM 82 CH". L111A1 This practice grenade has a small simulation charge (flash/bang) that imitates a live grenade for training purposes. It is distinguishable from the wholly inert L110 by being a much lighter blue and is fitted with a distinctive gold/orange plastic cap and safety lever. The body of the L111A1 is made of steel, is covered in a textured plastic material and has the word 'PRACTICE' embossed near the top of the body, near a top portion which is larger than the bushing on the live grenade. Like the L110 there is a large aperture in the bottom of the grenade which demonstrates it is not a live grenade, but in the L111A this aperture allow gas from the practice fuse to escape. Consisting of two parts, a grey reusable striker mechanism and an L162 practice fuse (which has a blue body with a brown base and is fitted with a silver washer) the practice fuse is fitted into the bottom of the reusable striker mechanism then the entire assembly
