KK, to do it right, the screwdriver blades must fit exactly the screws of your gun for thickness, width, and depth. If your are mechanically inclined, it is not difficult to buy driver bits and custom grind them for specific guns. Likewise, you can buy fancy turnscrews and custom grind. The chance are low of buying a set and having them fit properly. The chances of damaging screw slots with improperly fitting drivers is high. Proper fitting blades seriously trumps fancy handles.
