This man makes a Kydex type that configures in various places/angles depending on what you order, but once configured, it stays that way. Left side/Right side/butt up/butt down/chest rigs, etc. If you talk with him about it, he may be able to suggest ways to make the configuration more flexible for you = additional harness, etc.

I own one of these, and the comments on Kydex are correct, this holster is noisey. If you have a need to be quiet - this isn't the way to go.

Am not entirely certain this will fit your requirements, but it may give you some ideas.

Scroll down to Chest Rigs at the bottom of the holsters page.

Good luck.
