What happens here

Take the new replacement trigger kit, which typically includes new push-buttons and springs. First, insert the spring into the new trigger, followed by the push-button, ensuring the small, conical end of the push-button faces outward. Hold these in place with your thumb. Next, slide the new trigger assembly onto the gun's body. Once the trigger is in place, re-insert the retaining clips on both sides, making sure they snap securely. Finally, reattach the trigger guard/knuckle guard. Test the trigger lock mechanism to ensure it functions properly, confirming the successful replacement of the trigger.

Goal: This final step demonstrates how to install the new trigger mechanism, including its internal components, and reassemble the paint spray gun. It concludes with a check of the trigger's functionality.
