In a revolver having a frame, carrying a barrel and a revolving cylinder having multiple cartridge chambers therearound, the improvement comprising: a) a sliding sleeve positioned over an inner end portion of the barrel, said end portion of the barrel and inner diameter of the sliding sleeve closely mated; and, a) a sliding sleeve positioned over an inner end portion of the barrel, said end portion of the barrel and inner diameter of the sliding sleeve closely mated; and, b) said sliding sleeve having a front face having a central opening therethrough having an inner diameter nominally equivalent to marginally larger than, a bore through the barrel. Whereafter firing, the sliding sleeve is instantaneously driven back contacting its front face with the revolving cylinder, thereby eliminating any gap between the revolving cylinder and the barrel, preventing exploding gas from escaping therethrough, and substantially increasing bullet discharge velocity and energy. |
