D-Series AL Black Hard-Coat 7075-T6 Aluminum Button
available as an UPGRADE KIT
This can be used to UPGRADE or replace a D-Series Button, notably converting a Red Button to have a stronger button made with an all BLACK appearance.
*It is not recommended to change an SS button to a Black Hardcoat aluminum button on a Full Hardened SS version as this would be a downgrade in strength with a heavy handle resulting in a low lifetime of the button due to impacts.
