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 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 method of firing a firearm includes rotating a trigger to force a latch pin lever to move; 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 compact shotgun, a trigger assembly that could be used with such compact shotgun or other firearms, and an adapter and multipurpose mount that could be used with firearms or other devices are all disclosed. Each element has separate utility and combined utility in forming a combined under-mounted shotgun and long gun assembly.
