Howdy joec,
Welcome to the NCOWS Forum.
I'll repeat my answer from your same question posted up in the Shooter's Meeting.
The notched belt and the exposed trigger guard will disqualify it for NCOWS. As a minimum, the front leading edge of the trigger guard must be captured by the leather.
I think trying to pick a rig that advertises itself as designed specifically for Modern Fast Draw is at cross purposes with the philosophy of NCOWS.
I'd look into the work by Trailrider Leather, to be found here on CAS City.
