2 stage triggers (2ST) aren't dependent on pull weight for hammer energy like some SSTs are.
2STs allow you to have a much lighter final pull weight than a SST and still be safe.
I don't know of any "cons" for hunting with a 2ST. I have them on all my ARs anymore.
Excellent information Tyrone!….that’s a great post that directly addresses the OP’s question and cleared up some misinformation for me. 👍🏼
