:emoticon: I just got a Gamo Whisper Deluxe with the air venturi gas spring, and went to install the GRT III trigger. I wasn't paying attention to the great instructions and removed the wrong pin (the one that goes thru the safety spring. I realized my mistake and replaced the pin and installed the new trigger, but it won't cock. I then took a close look and found a spring that appears loose. It is a long U shaped spring at the top of the trigger assembly that probably came loose when I took out the wrong pin. I don't have a trigger schematic so I don't know how it attaches. Can anyone help? I feel really stupid because Charliedatuna included excellent instructions with the trigger.
