I've had my gunsmith adjust all my factory triggers for my tang safety and MKII M77's. Its easy to accomplish for someone knowledgeable in trigger tuning.

My tang safety rifles factory triggers have pull weight adjusted to 3.5lbs for big game. My Varmint tang safety has a long discontinued Canjar single set trigger, which is spectacular at 2lb non set & ounces in set.

My MKII rifles have Woolf trigger/sear spring kits and some polishing on the sear surface to 3.5lbs.

I had at one time a rare set trigger for the MKII made by the late Johannes Kepplinger of Austria. It was a work of art, needless to say!
