Abstract

Removal of a hammer from a trigger housing of a shotgun and subsequent replacement of the same or another hammer is facilitated by designing the firing mechanism such that, when the hammer is in its released position, neither the hammer nor the pivot pin mounting the hammer in the trigger housing is subjected to any biasing forces. The hammer can thus be removed, without interference from any other components of the firing mechanism, simply by removing the pivot pin. Such removal is made possible by providing a mainspring assembly which seats on the hammer when the hammer is cocked and unseats from the hammer and seats on another element, such as a seat formed on a sidewall of the trigger housing, when the hammer moves from its cocked to its released position. The removal process can be adapted for use in either a single barrel or a double barrel shotgun, and permits quick and easy conversion from pull firing to release firing.
