Applicants have disclosed an adjustable modular trigger assembly, and a related method, to avoid an unexpected firing of a long gun after an unintentional trigger pull. Applicants' preferred assembly comprises: a modular trigger housing, containing every trigger component, designed to be removably mounted within a lower firearm receiver; a trigger pull adjustment screw in a housing wall; and a sear force adjustment screw in another housing wall. During an intentional trigger pull, the shooter's finger pushes against a secondary trigger until it nestles within a slot of a non-coaxial primary trigger. Continued pulling on both triggers causes a sear to fall off a hammer notch and the firearm to discharge. In an unintentional trigger pull or jostling of the primary trigger, hooked protrusions (within the housing) of the second trigger and hammer engage to block the hammer from fully rotating, thereby avoiding discharge of the firearm. |

1. A modular trigger assembly for a long gun comprising:
a. the modular trigger assembly includes a modular trigger housing containing all the trigger components of the long gun, the trigger components comprising:
i. a primary trigger rotatably mounted between two sidewalls of the modular trigger housing on a stationary first pivot bushing, supported by the sidewalls, whereby the primary trigger can pivot about the stationary first pivot bushing;ii. the primary trigger has an elongated central slot in a trigger blade of the primary trigger;iii. a secondary trigger rotatably mounted, on a trigger blade pin, within the elongated central slot, whereby a trigger blade of the secondary trigger can pivot about the trigger blade pin and within the slot; andiv. a hammer rotatably mounted between the two sidewalls of the modular trigger housing on a second stationary pivot bushing, supported by the two sidewalls, whereby the hammer can pivot about the stationary second pivot bushing; b. attachment means for removably mounting the modular trigger assembly, and its housed trigger components, as a single unit within a lower receiver of a long gun; c. a sear adjustment means, within the modular trigger housing, for presetting an amount of force required to rotate the primary trigger; d. a trigger force adjustment means, contained in the modular housing, for adjusting the amount of force required to rotate the primary trigger, wherein the trigger force adjustment means comprises a set screw and a trigger force adjustment spring housed in a throughbore of the housing; and e. a safety means, within the modular trigger housing, for avoiding an unexpected discharge of the long gun upon an unintentional jostling of the first trigger. |
