About a year ago I bought a model 12 single shot target action, ordered a Shilen barrel in 6BR, and just recently bought a Savage F-class laminated stock. Went to put it together and the trigger hole spacing on the trigger guard is 3 1/2" and the stock is 3". I called Savage and they are sending me the right trigger guard. Went to my friends gun shop where I purchased it and all the Savage rifles he has in stock the trigger guards measure 3", the dual port target action that he has for sale has the same 3 1/2" trigger guard. Can anyone explain this, sorry for the long post.
