Tools your will need

• 2.8mm punch (or 7/64")
• Trigger Rebound Spring (TRS) Tool (sold on HKParts)

• Small hammer or mallet

• Locate the Safety Clamp on the right side of the frame
• Using a punch, push it up and out of the frame






Step 5
• Wiggle the Right-Side Slide Release Lever (up-and-down motion) and pull it out of the frame. Cover the TRS area with your hand before removing the Slide Release Lever because as soon as you pull out the lever, the TRS will come flying out. You do not want to misplace this spring!
