The Savage Accu-trigger tends to be a "love it or hate it" product. I personally enjoy them. I'm a bit of a traditionalist in that I don't enjoy barrel nut action types, and I'm saddened quite regularly the Savage actions are just so danged heavy, but I have NEVER seen a 10/110 or 12/112 which didn't shoot incredibly well, even with the box-stock factory barrels.
I do want to clarify on ONE very common complaint I have heard about the Savage accu-trigger which is NOT true, and a misunderstanding of an observation some owners have had with their rifles: If you pull the trigger, but not the blade, of a Savage accutrigger, it will move and will click - which many owners misinterpret as the striker being released. HOWEVER, if you do this in the field with a live round, the trigger will click, but the round will not fire. The click is NOT of the striker being fully released, but rather it is the sound of the striker slipping from the trigger to the blade safety. Stealing the line from Bob Lee Swagger - "the gun don't shoot." I have had requests by owners to replace or repair their Accu-triggers because they pulled the trigger without the blade and heard the click - which they assume means the safety had failed. It does not - that click is the sound of the safety properly functioning. ETA - as Ironworkerwill noted above, the appropriate resolution if you DID pull the trigger without the blade is to open and close the bolt to recock the striker, however, if you pull the blade fully (very heavy blade pull compared to normal operation), it will fire even without recocking.
Otherwise, most guys complaining about Savage Accu-triggers are just complaining for the sake of complaining - just like I complain about barrel nut actions.
