I took an individual picture of every part of the trigger assembly and edit them on Adobe Photoshop software. I scaled them all according to their actual unit sizes.

Post your comment if I have labeled some incorrectly.

Hey Willie:

You kinda got it right but where is the first stage contact?   Shocked There isn't one.  Therefore, there is no second stage in the factory trigger, only one. :0

Even though Gamo refers to their guns having a two stage trigger, it's not really a two stage at all. It's just a long pull to get to the first stage with no perception of contact with the first stage once you get there. The fat trigger pin is not the second stage.    Smiley

Also, the seer not only makes contact with the piston but latches on to the piston in the piston "latching/capture" slot.

Hey.... and I ain't pickn' on ya... Cool

Actually  Charlie I did not put any note on the 1st stage of the trigger pull since I am not so sure. I believe the 1st stage is where the trigger pin is touching the intermediate lever.  When I disassemble the trigger assembly I noticed that the intermediate lever's small curves on the bottom part perfectly aligns to the trigger pin and the fat trigger pin. If there is no purpose as to why they need to put those curves on the intermediate lever then its just another waste of factory time for such a small piece of metal (unless all these parts are press-punched).

No harm done, I did not even think for a single moment that you are picking on me. Hehehe. As I have said I am quite fascinated by the way an airgun works and I'd like to know more about it. Since I have an open G-1 in front of me and I personally own it and is responsible for it I can then observe, analyze, and make an inductive reasoning as to how it works.

I decided to post it so other newbies can see how the parts inside the trigger assembly are inter-connected. My only omission on the posted image was the 2nd stage screw adjustment because I'm having a hard time taking the measurements since I'm just using some plain old ruler and a small cheap caliper. Smiley

Perhaps it would be very nice if someone can enlighten us as to how all these parts really works in the actual design.

I don't come close to knowing enough to discuss the technical details....but your Photoshop diagram is just plain AWESOME. -M

The first and only stage is at the fat pin contact with the intermediate lever. As the trigger is pulled, the fat pin rises up against the intermediate lever and when moved far enough, disengages the sear. All of the trigger parts are stamped out and none of it is machined and most internal parts are designed with clearance purposes in mind. Depending on what gun clone and who the manufacturer is, the intermediate levers differs. It can be Spanish, Mexican, Brazilian, Turkish or Chinese. I've even seen years ago, a two part lamination intermediate lever and sear but I don't  remember what it was in. Many of them have little differences built into them but use the same basic design and same over all functioning measurements.

However, my point  is that the fat pin does not determine the second stage....cuz there ain't no second stage.

Just for the hell of it,...where does the long part of the intermediate pring supposed to be located,...under the sear pin,...or under the small circular peice stamped into the trigger body (looking down from the top of the trigger body on the right side?!? tjk
