Weatherby Vanguard S2 trigger
 

Looking to lessen the trigger pull on my .257 Wby Mag S2 (it's only 2 years old). What's the lowest a GS can drop this trigger to - 2.5 or 3 lbs? Or... should I just purchase a better trigger assy & install it? If the latter, which trigger do you recommend?

Buy a trigger. You'll get what you want and less chance of accidental discharges. Some gunsmiths are good at it and some are not.
