How to Increase Trigger Weight on a 1911

Instructions

    • 1

      Release the magazine and clear the chamber of any cartridges. When alterations are not being performed, turn the safety, located below the hammer, to the "on" position.

    • 2

      Pull the slide back two inches, or roughly 1/4 of its normal travel distance. Press down on the recoil plug and rotate the barrel bushing counter-clockwise.

    • 3

      Release the recoil plug slowly, careful not to allow the recoil spring to eject forcefully from the slide. Remove the plug and spring with care.

    • 4

      Cock the hammer, and pull the slide off the 1911. You now have access to the trigger assembly.

    • 5

      Remove the main center spring. Replace it with the heavier spring, making sure to attach the ends to the same trigger loops.

    • 6

      Bend the left spring inward to the desired tension level, if you require more trigger weight.

    • 7

      See a gunsmith if even more weight is desired.
