Q: Which DAA Magnetic Insert fits the Tanfoglio Stock III Xtreme?
A: The stock III insert. But, some light fitting may be required. It seems maybe Tanfoglio has made the rail even thicker/taller. DAA have seen customers who had to face of the block 1mm to get it to work well with their gun. However other customers have reported the Stock III insert worked perfectly well without any modification on their firearm.
