Abstract: A semiautomatic handgun has a frame, a barrel mounted on the frame and having a chamber for receiving a cartridge, a slide mounted on the frame and over the barrel and longitudinally movable relative to the frame and the barrel, a firing mechanism for striking the cartridge, and a trigger for releasing the firing mechanism. The barrel has a peripheral wall portion extending from the chamber, a cylindrical portion forming a front terminal end of the barrel, and a conical portion disposed between and contiguous with each of the peripheral wall portion and the cylindrical portion.

Abstract: A semiautomatic handgun has a frame and a barrel mounted on the frame. The barrel has a tubular portion defining a chamber for receiving a cartridge and a generally conical portion contiguous with the tubular portion. A slide is mounted on the frame and over the barrel and is longitudinally movable relative to the slide and the barrel. A trigger releases a firing mechanism for striking the cartridge.

Abstract: A handgun comprises a frame, a trigger pivotally mounted on the frame for movement between a rest position and a depressed position, and a hammer pivotally mounted on the frame in spaced relation to the trigger. A trigger bar is pivotally connected to the trigger and extends into operative relation with the hammer for cocking the hammer when the trigger is moved to the depressed position. A biasing member has a first end connected to the frame and a second end connected to the trigger bar for biasing the trigger bar in a direction into operative relationship with the hammer and in a direction for returning the trigger to the rest position from the depressed position.

Abstract: A handgun comprises a frame, a trigger mounted on the frame for movement between a rest position and a depressed position, a firing pin movable along a firing path between a cocked condition remote from a cartridge chamber and a fire condition proximate the cartridge chamber for firing a cartridge, and a biasing member for biasing the firing pin toward the fire condition. A transmission member is disposed between the trigger and the firing pin, via the firing path, and is responsive to depression of the trigger to displace the firing pin against the bias of the biasing member toward the cocked condition. A deflecting element deflects the transmission member out of the firing path of the firing pin to release the firing pin from the cocked condition and allow the firing pin to be propelled by the biasing member to the fire condition to fire the cartridge.
