Abstract: A baffle for use in a sound suppressor for a firearm utilizing proximal and distal faces with at least one joining wall positioned between the proximal and distal faces, and forming two expansion chambers between the proximal and distal faces. The joining wall has a bore hole and at least one opening in the wall itself and at least one opening from the bore hole into at least one of the expansion chambers positioned between the proximal and distal faces of the baffle. The joining wall may be either curvilinear, curvilinear stepped, planar or angled in shape. Openings are provided on the proximal face and the distal face of the baffle. At least one face of the baffle is either flat, curvilinear, curvilinear stepped, or asymmetrical to the axis of the baffle.
