I think it was Handloader, may have been Rifle, that long ago covered adjusting and reworking the tang safety trigger in a half page sidebar to a related article. I can only guess why I don't see articles like that much anymore. Worth buying a copy used or the PDF for reassurance if in doubt.
A first rate 2 lb trigger is certainly possible with little trouble and negligible expense - assuming roll pin punches, stones and lube of choice on hand; I liked Isky Cam Lube for a high pressure high moly lube but that's been hard to find in recent years - maybe a new roll pin.
It's easy enough to get results that match the effort - not difficult but maybe tedious - all the usual cautions apply.
