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.

A spring comprises a continuous wire member formed into a plurality of coils along a central axis. Each of the plurality of coils comprises a plurality of straight portions extending between bend portions each extending from one of the straight portions. The plurality of coils form a first spring body and a second spring body, each spring body comprising at least three coils and having a first end and a second end with the first end of the second spring body connected to the second end of the first spring body. In an unloaded state the first spring body has a first unique pitch distance between bend portions of each pair of adjacent coils and the first unique pitch distance decreases from the first end of the first spring body to the second end of the first spring body, and the second spring body has a second unique pitch distance between bend portions of each pair of adjacent coils and the second unique pitch distance increases from the first end of the second spring body to the second end of the second spring body.

The present disclosure provides apparatus for coupling an item to another item. The apparatus comprises a coupler mounted on the item and comprising a mating face having a plurality of catches thereon, the plurality of catches comprising at least one complementary pair of catches positioned and shaped to be engaged with corresponding catches of another coupler having an identical mating face when mating faces of two couplers are facewise engaged with and rotated relative to each other to align with each other. The coupler may be implemented as a floor plate of a magazine, as a clip, or in other forms.

A housing for a cartridge magazine for a firearm including an interior space consisting of a first and a second region. Between the first and the second region a transitional region is formed which connects the first and second region with one another. The inside surface of the front wall extends in the direction of the Z-axis in at least one region along a first circular path, the inside surface of the rear wall extends in at least one region in the direction of the Z-axis along a second circular path. The first region is designed for accommodation of four stacks of cartridges arranged directly adjoining one other and preferably offset in Z-direction relative to one another. The second region being designed for accommodation of two stacks of cartridges arranged directly adjoining one another and preferably offset in Z-direction relative to one another.
