My apologies if this has already been answered but I didn't see it. I see the Hoffman Trigger Jig which I plan on getting either way and I understand it's to provide proper clearance for the safety components but I was curious if the trigger modification is absolutely necessary for propper function and what triggers are recommended?

Most any "mils-spec" trigger profile will work. The cuts are required for the duel mode cam, and a minimum of polishing is required with the single mode cam.
