Abstract: A variable barrel camming system for a firearm includes a linearly reciprocating slide supported by a frame and a barrel removably coupled to the slide for movement therewith. A cam slot on the barrel slideably engages a cam pin mounted transversely in the frame. The slot includes a cam track surface having multiple angles and contours designed to control the motion and orientation of the barrel. When the firearm is discharged, the slide and barrel initially move rearward together under recoil forces generated. The pin slides forward in the slot over the cam track surface which is configured to rotate and uncouple the barrel from the slide which continues rearward alone. The cam track surface has a varying cam profile selected to gradually dissipate the kinetic energy of the barrel/slide unit in a controlled manner, thereby reducing the felt recoil imparted to a user compared to conventional cam systems.

Abstract: The present invention relates to a gun (1) with a pair of barrels (6?, 6?) flanking each other, each delimiting a cartridge chamber (12?, 12?). The gun further comprises a pair of firing pin tips (8?, 8?) for a cartridge (10?, 10?), movable towards the cartridge chambers (12?, 12?) by means of a firing device operated by a trigger (4?, 4?); such device acts on the firing pin tips to allow a substantially simultaneous advancement thereof. The invention also relates to a two row magazine for a double barrelled gun.

Abstract: This device is a trigger safety designed for use on the Colt model 1911 pistol and clones of the same design. The primary safety of the 1911 design is a thumb safety located on the left rear of the firearm. The location of the thumb safety is not an issue under normal circumstances, but in high stressful situations where the shooter is anticipating the firing of the firearm the thumb safety location is troublesome. Under stress the shooter may forget that the thumb safety is engaged, and may pull the trigger without the gun firing. The time needed to disengage the thumb safety may result in a life or death situation. This device incorporates a two stage safety in the trigger system that functions when all other safeties are in the off position. The location within the trigger eliminates the fractional second delay that the thumb safety may cause.

Abstract: An ambidextrous magazine catch for a firearm has a body movable on the frame of the firearm. A dog is rotatably mounted on the body.
