4. Step-by-Step: H4311 Lock Removal to Correct FTF

Tools needed:

Procedure:

  1. Unload and clear the firearm. Visually and physically inspect chamber and magazine well.
  2. Field strip to expose the trigger group or side plate (depending on model).
  3. Locate the H4311 lock assembly – usually a cylindrical block with a spring-loaded detent near the hammer pivot.
  4. Drive out the retaining pin securing the lock. Use a roll pin punch to avoid flaring the pin.
  5. Remove the lock cam and spring. Note orientation for potential reinstallation.
  6. Inspect for wear – Burrs or metal shavings on the lock often cause FTF. If present, clean with fine-grit abrasive (1000-grit) or replace the part.
  7. Test function without the lock: Reassemble the trigger group minus the H4311. Cycle the action manually. The hammer/striker should now fall crisply with each trigger pull.
  8. Optional fill: Some users insert a dummy plug or leave the cavity empty. Ensure no loose parts rattle into the sear.
