A conversion kit for converting a firearm to fire only non-lethal training ammunition comprises a barrel assembly and a slide assembly wherein the barrel assembly includes a barrel having a projection and the slide assembly includes a gate which interacts with the projection. The gate includes a member which is movable between a first ‘safe’ position wherein a firing pin of the firearm is blocked from impacting on a cartridge to a second ‘fire’ position wherein the firing pin is not blocked from impacting upon a cartridge in the chamber.
A conversion kit (1) for converting a firearm to fire a plurality of different types of non-lethal training ammunition comprises a single barrel (2) and a plurality of interchangeable barrel liners (3) which can be used in place of each other. The barrel (2) defines a bore (4) which receives one of the barrel liners (3) for firing non-lethal training ammunition and each barrel liner (3) is specific for a type of non-lethal training ammunition.

CONVERSION KIT HAVING INTERCHANGEABLE BARREL LINERS
A conversion kit (1) for converting a firearm to fire a plurality of different types of non- lethal training ammunition comprises a single barrel (2) and a plurality of interchangeable barrel liners (3) which can be used in place of each other. The barrel (2) defines a bore (4) which receives one of the barrel liners (3) for firing non-lethal training ammunition and each barrel liner (3) is specific for a type of non-lethal training ammunition.
An explosive composition for use in telescopically expanding non-lethal training ammunition comprises tetrazene and paraffin wax. The explosive composition can be used as a primer and/or as a source of energetic material in a telescopically expanding non-lethal training cartridge; it can be used to propel a projectile from a telescopically expanding non-lethal training cartridge; and/or it can be used to expand telescopically a non-lethal training cartridge within a host gun.

NON-LETHAL TELESCOPICALLY EXPANDING TRAINING CARTRIDGE FOR SELF LOADING GUNS
A cartridge for use in a gun comprises a case, a gas generator, a piston, a stopper, and at least one channel for the passage of gas in and / or around the stopper Wherein the piston is axially slideably contained in the case, the gas generator is located within the case adjacent a first end of the case, and the stopper is slideably contained within the piston for closing the at least one channel.
A cartridge for non-lethal applications comprises a posterior portion 1 which extends axially to provide a cylindrical casing. An anterior portion comprises of a nose portion 2 with a centrally located recess 8 for receiving a projectile, and an axially extending piston 3 which is slidably engaged in the chamber defined by the cylindrical casing 1. A posterior primer 4 is located to the end of the posterior portion which is most distal to the nose portion 2. An anterior primer 5 sits just behind the recess 8 of the nose portion 2. A plastic striker is located in the chamber defined by the cylindrical casing 1 and comprises of a sealing flange portion 6 and striking nose portion 7. The striking nose portion 7 locates snugly but slidably in a second chamber provided axially within the piston 3. In use, the posterior primer 4 releases gaseous product which drives the striker 7 against the anterior primer 5 whilst simultaneously causing telescopic extension of the cartridge which in turn results in recycling of a host firearm.
