Abstract: A firearm has a frame, a pivot connection connected to the frame, an elongated trigger lever coupled to the pivot connection and movable in a first direction between a rest position and an actuated position, the trigger lever including a first portion and a second portion, the first and second portions of the trigger lever being configured to receive first and second fingers of a user, and a trigger biasing structure including one or more bias springs to apply a force to the trigger lever to bias the trigger lever in a second direction opposite the first direction, and wherein a force applied to move the trigger lever in the first direction is the sum of an applied force multiplied by the distance between the first portion and the pivot connection and the applied force multiplied by the distance between the second portion and the pivot connection.

Abstract: A double-barreled revolver has a frame, a trigger lever having a first end connected to the frame and movable between a forward rest position and a rearward actuated position, the trigger lever having a free end extending away from the frame and opposite the first end, a guard element forward of the trigger lever and having an upper end connected to the frame and a downwardly depending lower end, and the free end of the trigger lever being separated from the lower end of the guard element by a limited gap, such that the frame, trigger lever and guard element collectively define a protected trigger space. The gap may be less than 0.9 cm such that a user's finger may not enter the trigger space except from a lateral direction. The trigger lever may have an exposed actuation portion configured to be actuated by two fingers.

Abstract: A double-barreled bullpup pump-action shotgun has a frame with two forward-extending barrels arranged side-by-side, a pair of tube magazines, each positioned beneath a respective barrel, an action attached to the frame and operable to load ammunition from the tube magazines to the barrels, and a trigger assembly attached to the frame, the action being located at least in part behind the trigger assembly, and the trigger assembly including a trigger linkage to connect the trigger assembly to the action and to operate the hammers behind the bolts. The action may be a pump action. The trigger assembly may include a plurality of hammer trips, each having a sloped forward surface. The trigger assembly may include a plurality of sears having tails, and the sloped surfaces of the hammer trips may lift the tails of the sears during a portion of a complete cycle of the action.

Abstract: A side lock action firearm has a frame with an attached side lock action. The frame includes a rearwardly protruding portion including a mating feature. A stock including a mating element is removably connected to the frame when the mating element is engaged with the mating feature. The mating feature may be a threaded boss. The mating element may be a draw bolt. A forward portion of the stock may be shaped to closely receive the rearwardly protruding portion of the frame. The stock may include a central bore, and the draw bolt may be received by the central bore in the stock.
