Tuning HW110 trigger

They caution against adjusting it. It's one of the HW110 and 100 and 44 strongest attributes.

I have never even contemplated trying to adjust any of their perfect triggers (HEAVIER) because they aren't even true light match grade like my Steyrs and FWB and Anshutz and Walther or even RAW Daystate electronic and so on. Even my relatively cheapish CZ Bruno Aerons match triggers are lighter and Chinese AA CZ Alpha Proj pistol trigger copy is better than the real thing (Listone Victor at 1/3 to 1/4 the price).
 
I was going to offer advice based on HW100 experience, but after looking at some HW110 information and pictures, it's obvious they are totally different. I think, if you remove the action, then remove the trigger guard, the weight adjustment screw should be clearly visible. The spring was very easy to see in one of the photos I saw, and I assume one end is attached to a lever that is moved by an adjusting screw.
