Even though other Savage models claim to use 5/32 headed screws, my front two screws measure 3/16. So when I go back to the rear screw that also holds on the pistol grip, it is note the same size. Since I don't have a set on long drivers, I would like to buy the correct size as I doubt Menards will let me bring in the gun to try out the different driver sizes. (I am assuming that this rear screw and the foot pounds it is tightened is the screw I have read about that plays an important part of the accuracy of a Stealth.)
