US Patent 10330413 Half-cock trigger safety assembly

Trigger assemblies that preserve the integrity of the trigger sear surface when the trigger assembly enters a “half-cocked”, safety configuration are disclosed. In certain embodiments, a trigger safety engagement surface engages a hammer safety engagement surface in the safety configuration, preventing the hammer from rotating into contact with a firing pin. In some instances, the trigger sear surface is suspended within a safety recess (e.g., a notch) of the hammer and free of contact with the hammer when the trigger assembly is in the safety configuration.
