In a multiple-barrel firearm with removable lock housing, the two axially moveable strikers are arranged in superposed relationship, preferably being angular and provided with grooves or edges; this arrangement permits, even in case of only one solid sidewall, a favorable guidance of the strikers and contributes considerably toward making the lock housing very narrow. Since, in this firearm, the movement of a cocking bar just as the movement of firing pins takes place approximately in parallel to the movement of the strikers, the advantage is obtained in addition to a relatively simple structure that the energy for cocking coil springs guided by means of guide pins can be at a minimum as well. The guide pins connected with the strikers also take over safety functions.

The fixation of the barrel housing to the breech housing in a break-open gun is controlled by a top lever breechblock, the bottom of which carries, in a groove, countersunk, a connecting member with an eccentric tenon in a displaceable fashion, the tenon being insertable in one of two bores in a control part, and the control part driving the breechblock wedge or wedges, wherein at least one spring between the control part and the breechblock wedge absorbs, when the control wedge is not worn, a distance increment so that the breechblock lever during locking can always go back into a central position. The gun can readily be refitted from a right-hand shooter to a left-hand shooter: the connecting member is rotated by 180.degree. and inserted in the opposite bore, the spring stop is likewise turned, and the breech spring is exchanged with the pressure bolt and the stop bolt.

The reliability of a cartridge ejection device can be improved by the interposition of a readily deactivatable control flap, arranged on the outside of a monobloc unit, between a control bolt and a cartridge ejector of a break-open gun-housing of at least one barrel. The arrangement has the advantage wherein when no shot has been fired, the ejector will move into the extended position gradually during tilting of the barrel. When a shot has been fired, the ejector will remained tensioned until the barrel has been entirely tilted. Another advantageous feature is obtained by constructing the cartridge ejector of two parts coupled by way of a spring, namely a cartridge extractor and an extractor element, because thereby stress peaks can be further reduced and the cartridge extractor can already be entirely in the retracted position even before the barrel is completely closed.
