Recently acquired a used Weatherby Vanguard Sub-MOA and it came with what has to be the worst trigger I have ever tried to pull -- heavy, gritty, just awful. Maybe that's why it was for sale. Last night I installed a new Timney. It took a screwdriver and about 4 minutes and it's like a new rifle and the trigger is great. If you're thinking about a new trigger, do it, it's easy and worth it.
