Appendix carry has a lot of value, at least in some settings. However, that holster is complete clownshoes, and any instructor or FTO who saw it should want to apply aggressive remedial wall to wall counseling. I'm so horrified by it I have never give his revolver a close look.

BTW, a forehead shot is not reliable with a pistol - the target area for a frontal shot to the head is actually a face shot. Draw a triangle using the outer corners of the eyes and the bottom of the nostrils. The other oddity is that it is actually easier to teach reasonable fighting skill with most autopistols than it is with a revolver. Unless he is ND-ing, there would be some real drawbacks to having a revolver used by NDP.
