ABSTRACT:
A gas seal revolver which includes a barrel having a longitudinal bore therethrough, a rotatably mounted cylinder positioned adjacent to the barrel and having a plurality of chambers therein, and a sealing and aligning structure oriented between the barrel and the cylinder to thereby form a leak resistant gas seal when the barrel is moved against the end face of the cylinder. The barrel and cylinder assembly are movable mounted to the frame such that the revolver may be tipped open for easy loading and cleaning of the operative parts contained therein. The revolver also includes an indexing mechanism which cooperates with notches along the outer periphery of the cylinder in order to incrementally move the cylinder so that the chambers are moved into and out of preliminary alignment with the barrel bore. The barrel is also prevented from being opened during any phase of trigger motion thereby ensuring that the operator will not open the barrel during the firing cycle. In the rest (or idle) position, the chambers are not in alignment with the firing pin or the barrel so that any blow to the hammer, which might occur, such as if the revolver is dropped, will not strike a primer of a cartridge.
