I recently bought a used Model 11 300wsm and the safety stops the trigger in 2nd and 3rd position, it just does not lock the bolt in the 3rd. After some searching I thought I might find a safety adjustment screw behind the trigger, but this just has a spring. No screw. This model has an accutrigger, I am not sure if all of the 11's do or not. I apologize if this has been asked before and I missed it. Does anyone know what I can do to fix this?
