摘要	A reduced signature weapon cartridge is provided which, when fired, produces little or no muzzle blast or noise signature. In particular, a reduced signature weapon cartridge of the present invention comprises a movable piston disposed within the cartridge, disposed in between the high pressure chamber and the projectile. When fired, propellant gases rapidly force the piston forward within the cartridge case, thereby launching the projectile at a subsonic velocity, thereby eliminating the conventional noise signature associated with supersonic velocities. Thereafter, the propellant gases are slowly released from the cartridge case via perforations formed within the piston, grooves formed in the periphery of the piston, or via a gap between the piston and cartridge wall, thereby reducing or eliminating the conventional muzzle blast.
