Abstract: A recoil reducing device for use with firearms including handguns and rifles which includes a core and a sleeve that surrounds the core. The core and the sleeve each have a plurality of radially directed openings along their lengths that are cooperatively aligned with respect to each other. The openings are oriented with respect to a central bore of the core such that combustion gases generated by firing the firearm, noise and any unburnt gunpowder are directed away from a shooter, and recoil and muzzle rise of a firearm are substantially reduced.
