    • A firearm has a frame with an interchangeable barrel that is mounted to the frame through a tool-less knockdown pin. The barrel has ports in a smooth-bore section and no ports in a rifled-bore section, and the ports are progressively spaced, with the ports closest to the rifled-bore section having a greater distance between the ports than the ports closest to the muzzle. Preferably, the firearm is a multi-chamber design such as a revolver with a firing cylinder or a multi-barrel breech-loader that holds multiple rounds of ammunition together with a storage-firing clip while stored in an ammunition compartment and also when loaded into the firing chambers and discharged by the firearm. The frame preferably has a trigger mechanism with a sear assembly that includes a block assembly with a wedge block that translates on a guide rod and a disconnect block that is supported by a disconnect rest.
