Capt. John,
I very recently installed the trigger that Weatherby sells on their web sight in my 1970's era Vanguard aka as the copy of the Sako. It required a some
minor fitting but went in and works perfectly. It is a 3 position safety all the way back locks the bolt and trigger middle position unlocks the bolt for
unloading trigger is still locked and of course forward is fire at will. The one drawback that some folks may not like is that it is a 2 stage trigger that has
some very light take up prior to trigger release. Also it appears to be adjustable for weight of pull. Mine has a 3 pound pull at the factory setting which
is fine for me. I never did like the original trigger and had problems with installing the Timney after market trigger. So with a price that wasn't to bad
I decided to try this it works and I consider it an improvement over the original trigger.
Good luck
Dave
