Laursen Revolver
The Laursen revolver is a common version of a Laursen Rifle, using individual chambers to hold Vaplium canisters simultaneously, and being able to fire all chambers in relatively short order. It uses a hexagonally rifled barrel with a 1-50" twist attached to a cylinder and typically, either a wooden grip or stock. The firing mechanism consists of a manually cocked hammer. In typical operation, the user will open the loading gate, use an ejection rod to push the existing cartridge out if needed, and then slide a Vaplium canister into the chamber, followed by a bullet. The canister has a rim facing towards the bullet that prevents it from being loaded in the wrong orientation. Once the bullet is snug with the canister, the user rotates the cylinder and continues filling chambers.
Once the user is ready to fire, he will cock the hammer back, and then pull the trigger. As the trigger is pulled, the cylinder rotates flush with the barrel, and the hammer releases, directly striking the back of the canister. This causes a catastrophic pressure change that detonates the Vaplium. Due to the cartridge construction, the end facing the bullet is significantly structurally weaker, and explodes outwards towards the bullet. The force of the detonation propels the bullet forward, and the bullet is propelled out of the barrel. As the trigger is released, it rotates the next cylinder into position.
The canisters are typically stored in a small glass sphere which is shattered (known as deglassing) before they are to be used, as the metal used will deform under pressure. Typically, a revolver is fully loaded before going into combat, and is seldom reloaded in combat. If it must be, the user will typically use a specialized spring loaded tool calibrated to only shatter the glass, but this takes a few second for even an experienced user. Typically, a revolver can be left safely loaded with deglassed canisters due to the relative safety of the cylinder.
