Sharpest glass breaking triggers have been a few hand made one offs stemming back last 22 years, and proper two stage too.
Next best production wise the current 5065 Anchutz trigger.
LG200/300/400 Tesro are pretty good and rate 2nd best.
Pneumatic Fens P75, P70, P800
Old 5020D Anchutz trigger as fitted to the pre 2004 2002/2020/2025 and current ISP
All above are proper two stage except the Walther/Tesro but all setup from factory as a single stage unit.
Worst Chinese B10-45 gets harder the more air is in, like GC2
