Applicant has disclosed an improved trigger assembly for firearms, and a related method, to avoid premature firing after an unintentional trigger rotation, especially where light trigger pulls have previously been set. In the preferred embodiment, Applicant's trigger assembly has two triggers: a slotted primary trigger and a secondary trigger which can pivot into the slot. During an intentional trigger pull, the shooter's finger initially pushes against the secondary trigger until it pivots and nestles within the primary trigger's slot. Continued pulling on both the secondary and primary triggers causes a hammer to rotate off a sear, thereby allowing the firearm to discharge. In an unintentional trigger rotation, where the secondary trigger is not pulled back enough to nestle within the primary trigger's slot: an upper portion of the secondary trigger (unseen within the housing) constrains a protrusion on a spring-biased mainspring guide. This blocks movement of the mainspring guide and prevents the hammer from rotating sufficiently for discharge. |
