A firing mechanism for a firearm includes a frame, a barrel attached to the frame, a cylinder attached to the frame and including a chamber that is alignable with the barrel, and a latch pin in direct contact with the cylinder that moves forward to force the cylinder forward to directly contact the chamber with the barrel when a trigger is pulled.

A handgun that can be configured to different firing settings. The settings provide for selectively firing a single round or two or more rounds. The handgun can include a body with two or more barrels. The handgun can also include a cylinder with different chambers positioned into groups that align with the barrels. The handgun includes a switch that can be moved to configure the handgun between the different settings.

An apparatus to minimize short stroke in a revolver is provided wherein a first end of the transfer bar is pivotably disposed on the trigger adjacent to the first end of a hand, the second end of the transfer bar disposed adjacent to the firing pin of the hammer, wherein during a firing cycle, prior to the revolver being brought back to the ready-to-fire position, the trigger cannot be depressed until the trigger is first fully undepressed, wherein the second end of the transfer bar engages a transfer bar blocking surface of the hammer slot in the hammer to prevent the trigger from being fully depressed.

A firearm is provided comprising a frame which defines a forward aperture. A cylinder is mounted rotatably to the frame to rotate on a cylinder axis. The cylinder defines a plurality of passages each at a common radius from the axis, each passage includes a chamber and a rifled bore. At least one of the passages is being chambered for a different caliber than at least one other of the passages.

The invention belongs to a weapon namely to the automatic weapons without ammunition. Particularly it belongs to the weapons using the energy of the explosion mixture gas, flammable liquid or other mixture in the combustion chamber as a mover of bullets. A weapon without ammunition, arranged according to the bullpup scheme, contains: the barrel; the receiver in the form of a cylinder rolling in a rectangular box; the trigger mechanism; the piston for supplying combustible mixture to the combustion chamber and for cooking the compressed air in the mixing tube. This piston is connected by a rod with the piston gas tube; the cylinder full of compressed gas, flammable liquid or other mixture; the drum with several chambers of internal combustion in the form of elongated cylinders. When moving to the trunk a drum is pushed by the nozzle of the lower chamber in the rear part of the bullet and toilet it in the trunk from the top of the camera. This occurs by the rotation around its own axis and longitudinal movement along this axis; the ignition mechanism consisting of a piezoelectric element and the spark; the secondary ignition system consists of a battery and a capacitor; the venting mechanism with the gas tube and piston, in which the gases are directed toward the muzzle; the return mechanism; the multi-function ammunition cartridge of extended capacity, feeding the bullets into the machine vertically. There is a function of the butt, and when you transfer the spare magazines on the body of the soldier there is a function of armor plates.
