I recently bought a 629-3 that came with a Leupold scope mount and rings on the gun, no metallic rear sight. Just ordered the rear sight from S&W and asked if they had the grub screws to block the pre-drilled holes that I won't be using when the metallic sight is mounted. They didn't have any. Would anyone know the thread pitch/diameter/length for those grub screws?
and thanks in advance,
