Abstract: A suppressor for a firearm is provided, including a tubular body couplable to a barrel of the firearm. The body includes a bore that provides a pathway for a projectile to travel through the suppressor, the bore including an inlet section, a central section and an outlet section; and a first passageway that extends axially along a length of the body and is disposed externally of the bore and is in fluid communication with the inlet section. When the suppressor is coupled to the firearm, expansion gases enter the bore through the inlet section and propel the projectile along the central section and through the outlet section, with a first flow of expansion gases passing from the inlet section into the first passageway before being expelled from the body. Energy is dissipated along the first passageway and sound levels associated with the firing of the projectile are reduced.
