This is a custom grip screw designed by Henning that works with all the Tanfoglio / EAA Witness frames. It has a lower profile so you won’t feel the grip screws dig into your hand like the factory screws do. And with the T10 Torx they are easier to install and no danger of the screw driver slipping into the grip panels when installing .
Grip Screws: 303 Stainless T10 Torx Small Head (Set of 2)
Small Profile Head, Head Diameter 0.225″ which fits all grips
