ABSTRACT:
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.
