A firearm cartridge with a pre-pressurizing charge and a main propellant charge. The pre-pressurizing charge is located adjacent the rear end of the projectile. The pre-pressurizing charge can burn and exert pressure on the main propellant charge without igniting the main propellant charge.

Firearm cartridge with pre-pressurizing charge

An light-energy initiated firing system for a firearm in which optical light-conducting fibers extend from a source of high frequency energy to adjacent a cartridge so that energy passes through the fibers will pass into the cartridge and initiate a propellant therein. The firearm cartridge may include a ignition composition (e.g., a primer) position forward of at least part of the propellant and be constructed so that high frequency (e.g., laser) energy will pass into the cartridge and initiate the forward-positioned propellant. The system includes safety systems for interrupting the energy path to prevent primer initiation when the action of the firearm is not in battery or when such initiation otherwise is undesired.

Firearm safety system

A firearm cartridge magazine comprising a housing and a battery. The magazine is adapted to be removably connected to a firearm to house and dispense firearm cartridges. The battery can supply power to the firearm such as for a battery operated firing system. In a preferred embodiment, the battery is the sole power source for the firearm such that the firearm can only fire when the magazine is properly connected to the firearm.
