Claim:
A shotgun having a trigger and a muzzle, the shotgun comprising: a telescoping barrel; the telescoping barrel comprising a plurality of concentric barrel sections slidably engaged together; the plurality of concentric barrel sections comprising: an inner barrel section that is nearer to the trigger than any of the other barrel sections in the plurality of barrel sections; and an outer barrel section forming the muzzle; the inner barrel section having a first diameter smaller than a second diameter of the outer barrel section; a grip attached to the outer barrel section, such that a shooter may telescope the outer barrel section by grasping the grip and exerting force to slide the outer barrel section in a direction that is either outward with respect to the inner barrel section setting the telescoping barrel in an extended position, or inward with respect to the inner barrel section setting the telescoping barrel in a contracted position; and a locking pin that may be manipulated to secure or release one or more concentric barrel sections in the plurality of concentric barrel sections for telescopic movement; and a spring to bias the plurality of concentric barrel sections in an extended or shortened configuration once the locking in is released.
