ABSTRACT:
A firearm has a plurality of parallel barrels arranged uniformly circumfetially about a center axis. A hammer is translational from a cocked position to a fire position along said center axis. It has a firing pin offset from the center axis in correspondence to the spacing of the barrels from the center axis. The hammer is pivotal about said center axis during cocking to advance the firing pin from an aligned position in respect of one barrel to an aligned position in respect of a succeeding barrel. The firearm comprises a trigger guided for translation rearwardly from a rest position. A sear, connected to the trigger via a ramp formation, is arranged, on depression of the trigger, to engage the hammer to cock it. Progressive depression of the trigger progressively displaces the sear via the ramp formation to a release position in which the hammer is released to translate from its cocked position to its fire position under resilient bias.
