Abstract
A puncture mechanism that is configured to puncture a seal provided over a mouth of a canister of compressed gas received within a less-lethal device to propel a projectile from the less-lethal device when a trigger mechanism of the less-lethal device is actuated by a user. The puncture mechanism includes a displaceable body that has a piercing mechanism which is configured to pierce the seal provided over a mouth of the canister. The puncture mechanism further includes an actuation arrangement, which comprises a trigger mechanism, for displacing the displaceable body towards the canister whereby the piercing mechanism pierces a seal of the canister and compressed gas flows into a barrel of the less-lethal device to propel the projectile from the less-lethal device.
