A method of firing a firearm includes compressing a main spring to rotate a latch pin lever; forcing a latch pin forward by the latch pin lever to force a cylinder forward toward a barrel; sealing or substantially sealing the barrel and the cylinder; and releasing a hammer to strike a cartridge while the barrel and the cylinder are sealed.

A self-defense device with a body, a gun barrel, a trigger assembly, at least one forward light, and a switch is disclosed. The body is held by a human hand. The gun barrel can be positioned in the body and include an entry port and an exit port. The trigger assembly includes a trigger and a firing pin. The firing pin is moveable to engage a round in the barrel. The light can be exposed on an outer surface of the body. The light is positioned such that light emitted by the light projects forward, along the axis of the barrel. The switch can selectively activate and deactivate the light. The switch and the trigger are positioned close to one another so as to be concurrently engageable by a single human hand.

A firing mechanism for a firearm includes a trigger, a forcing structure, and a spring within a cylinder, wherein while the trigger is pulled, the forcing structure moves to force the cylinder to contact a barrel and to force the spring to compress, and while the trigger is returned to an idle position, the forcing structure moves to allow the spring to decompress and to force the cylinder away from the barrel.

An improved revolver is disclosed. The revolver has a hollow handle and a cartridge cylinder. The revolver includes a magazine clip, releasably insertable into an interior region of the handle, and at least two cartridge sets contained within the clip. Each cartridge clip, ordinarily cylindrical in shape and unable to be inserted into the magazine clip, is easily compressed by a user into an elliptical shape, which is an improvement designed to enable quick loading, unloading, and reloading of cartridges into the magazine clip and thereafter into the cylinder of the revolver.

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.
