ABSTRACT:
A firearm having interchangeable barrels and ammunition cylinders for changing the caliber of ammunition used therewith includes a plurality of ammunition cylinders and a plurality of barrels, each barrel being threadedly mountable on the firearm frame with each barrel including a longitudinal barrel extension for interfering with the mounting and revolution of the ammunition cylinders for ammunition having a larger caliber than that of the respective barrel, and the improvement therein includes alignment marks on the barrels and frame for alignment under the full threaded engagement of each barrel in the frame, a plurality of sight ribs with each sight rib corresponding to a different barrel, means for attaching each sight rib to its corresponding barrel at a predetermined location to enable each sight rib to its corresponding barrel at a predetermined location to enable each sight rib to be operatively oriented with the rear sight for aiming the firearm when each barrel is fully threadedly engaged in the frame bore, and means for inhibiting attachment of each sight rib to its corresponding barrel when such barrel is only partially engaged in the frame bore for allowing attachment of each sight rib only after its corresponding barrel is fully threadedly engaged in the frame bore.
