The (legacy) Vangaurds have adjustable triggers. Consult the owner's manual first. After taking the action off the stock and checking the manual you'll see the two screws that are near the trigger. One is for you to adjust, if you want to try, and leave the other one alone.
If the adjustment doesn't turn out the way you want it, ask what a smith can do for you. It might be what you're wanting. If that doesn't work, get a Timney trigger.
I've adjusted the triggers on two of my Vanguards and they're both good. They're nothing like the S2 Vangaurd trigger, but they good anyway.
