An outflow opening extends through the barrel transversely of its axial direction and is in flow communication with the combustion chamber. A slide, including a sealing piston, is displaceably positioned within the outflow opening the regulating the flow of explosive gases out of the combustion chamber. A handle is engaged with the slide for selectively positioning the sealing piston in the outflow opening.
