Firearm action mechanism
View Patent ↗A pistol comprising of a frame, a slide operable to reciprocate with respect to the frame, a barrel connected to the slide, with a cylinder defining a plurality of chambers connected to the slide to reciprocate with the slide, and operable to rotate with respect to the slide. The frame defines an ammunition compartment including an upper most ammunition position. The cylinder has a first chamber registered with the barrel, and a second chamber registered with the upper most ammunition position, such that in response to a cartridge in the first chamber discharging, the slide reciprocates to a recoil position to eject the cartridge case and to cause the upper most cartridge to enter the second chamber. In response to return of the slide to battery, the cylinder rotates to register the second chamber and cartridge, to alignment with the barrel for subsequent discharge.
