I wasn't satisfied with the retention of my Regulator sheath with the snaps unfastened. So I made a kydex insert. I used chicago screws to fasten it and then removed the second snap strap.

I wanted to be able to mount it upsidedown on my work in progress Walter Mitty tac vest. Turns out it is a little long, to where it would be difficult to shoulder a long gun on the weak shoulder and may allso interfere with handgun or pouch placement underneath. oh well I'll figure that out later.
