A sound suppressor for a firearm comprises a cylindrical housing having a rear end cap attached to the housing and having means for mounting to the muzzle of a firearm, a front end cap attached to the housing and having a centrally positioned aperture, and at least one baffle element positioned within the housing between the rear end cap and front end cap. The baffle element comprises a flat plate with an integral rearward-protruding cone with the cone having an entrance aperture and an exit aperture, with the cone having an elongated aperture that extends from the entrance aperture toward the flat plate. An initial coaxial spacer element is positioned between the rear end cap and the baffle element, with the initial coaxial spacer element having at least one gas port and at least one notch at an edge of the initial coaxial spacer element. Inner and outer expansion chambers are formed between the rear end cap, the initial coaxial spacer element and the baffle element. A coaxial spacer element is positioned between the front end cap and the baffle element, and the coaxial spacer element has at least one gas port and at least one notch at an edge of the coaxial spacer element. Inner and outer expansion chambers are formed between the baffle element, the coaxial spacer element and the front end cap.
