Improved cylinder locking means for a small, single action revolver which is positioned entirely within the body of the revolver and operates with the hammer and hand to release the cylinder during cocking of the hammer and to lock the cylinder against turning during firing of the revolver and when the hammer is in a forward position. A spring biased latch member is pivotally connected between its ends to the frame of the revolver so that one end of the latch is positioned adjacent to the lower side of the cylinder and is adapted to make releasable engagement with the cylinder. The other end of the latch is positioned close to one of the sides of the hammer. An actuating member projects from the hammer or hand and is adapted to strike the underside of the end of the latch during the initial cocking movement of the hammer and pivot the latch to release the cylinder for rotation. As the hammer approaches the fully cocked position, the actuating member escapes beyond the end of the latch member, so that the latch member moves into engagement with the cylinder and locks the cylinder in proper firing position. As the revolver is fired, the actuating member is biased to slide past the latch to again be in position to strike the underside of the latch during a succeeding cocking movement of the hammer.
