A muzzleloading firearm for engaging a firing pin to discharge a primer includes a trigger plate connected between a front stock and a rear stock, with a central cavity traversing the trigger plate to support a sear and a trigger in mechanical communication with the sear. A hammer assembly is pivotally mounted to the trigger plate to rotate between a cocked position and a resting position, and includes a base extending into the central cavity. The base includes an upper arcuate surface opposite a lower locking surface having a shoulder. A hammer head member is connected to the upper arcuate surface to engage a firing pin. A rolling breechblock is pivotally attached to the plate between a retracted loading position and a firing position, and has a curved upper surface to engage the arcuate surface of the hammer assembly when moving between the loading position and the firing position to force the distal end of the sear to engage shoulder of the base. The firearm also includes a hammer safety pivotally connected to the hammer head member to move between a hammer firing position engaging the firing pin and a hammer safety position engaging the rolling breechblock.
