L109A1
In September 2000 a six-year contract with Swiss Ammunition Enterprise Corporation (a RUAG subsidiary) was announced, committing the UK to purchased circa 363,000 grenades for combat and live training, first deliveries scheduled for March 2001.
The L109 is the British designation for the HG 85. It differs from the HG 85 in that it has a special safety clip (matte black in colour, which is similar to the safety clip on the American M67 grenade.
L110A1
The L110 (Drill Grenade) 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.
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 and is covered in a textured plastic material with and has the word 'PRACTICE' embossed near the top of the body, near a top portion 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 fuze to escape. Consisting of two parts, a grey reusable striker mechanism and an L162 practice fuze (which has a blue body with a brown base and is fitted with a silver washer) the practice fuze is fitted into the bottom of the reusable striker mechanism then the entire assembly is screwed into the top of the grenade. In this version the safety lever is attached by a plastic strap to prevent loss, the entire unit, apart from the expended L162 practice fuze, being reused.
Markings, again in white, include 'GREN HAND PRAC L111A1', a manufacturers mark 'SM' meaning Swiss Munitions, and a lot number.
Nr300
The Nr300 is the Dutch designation for the HG 85. It is exactly like the L109.
