Pre Tapped Firearm Mounting

The Zadik Precision Thumb Rest is designed to be installed using the hole patterns as described HERE. Once your existing hole pattern and screw sized has been determined, You can order the correct thumb rest.

The Zadik Precision Thumb Rest will fit the 3 hole C-MORE pattern (.750 on center) using only the FIRST and THIRD Holes with 5-40 screws. This is sufficient to securely mount our thumb rest.

If using the Tanfoglio 4 hole pattern ( 10mm / .397 on center) The first 3 holes or last 3 holes can be used with 4MM x .07 screws. The choice is yours.
