  • Trigger energy absorption apparatus and method
    Patent number: 11385010
    Abstract: An elastomer shock absorber for the trigger assembly of a firearm utilizing an elastomer shock absorber positioned between a moving part of the trigger assembly and the frame assembly. Adhesive mounting of the elastomer to the back of the trigger or positioning the elastomer internal to the frame assembly both provide significant reductions in the shock transfer of trigger energy to the gun body, thereby increasing the accuracy of the firearm.
