Molle attachable holster for chest rigs

[JDBAK]

Gents, I’m interested in these chest rig systems that allow a pistol holster to be mounted to a bino pouch via molle.
Meaning there’s a molle panel below the bino pouch to attach a holster.
I think Kifaru and Elberstock do this.

Question: who makes suitable holsters for this kind of set up? And what gear is needed to attach?

Thanks
