as i just picked up a trg 22 with the new 2013 trigger assembly upgrade and noticed it didnt look like the old diagram in the manual that came with it, i went looking and found this thread. i thought i would share my experience. i believe i have it figured out. i discovered that contrary to the old manual you do not have to remove the trigger assembly to adjust either first stage or second stage weight. i did run into some issues. here is what i suggest. you can get to both the first and second stage trigger screw heads through the hole in the bottom of the trigger guard. i recommend you first first tighten down both screws all the way. i did that and first stage was at 2 lbs and second stage was at 4 lbs. then i gradually backed both screws off by turning counterclockwise in a series of tests. back off the 1st stage screw first and then the 2nd stage screw. first try got 1st stage down to 1.5 lbs and 2nd down to 2.5. as someone noted in this thread it appears the 2nd stage screw head is just a bit below/the edge is under the 1st stage screw head [maybe to keep the 2nd stage screw from falling out?]. little by little i got the 1st stage down to .75lbs and the second stage down to 1.75 lbs and it is very comfortable there. i will test fire tomorrow to see if there are any issues with the setup. one upsetting thing that did occue was when the second stage screw came all the way out. it took a bit of manipulating but I was able to get it going again under the 1st stage screw [but did create one of those oh sh!@#$T moments]. seems there is no need to remove the trigger assembly at all to adjust 1st and 2nd stage weights. the manual that comes with the gun is useless on this issue [hasnt been updated!]
