FHF Pro-M and M1 question, or recommend me an RF pouch

[quartermaster]

I have an FHF Pro-M harness and I'm in the market for a rangefinder pouch to fit my Crossfire 1400 HD.
I'm not a huge fan of the redesigned rangefinder 2.0 pouch since the fixed loop seems like it'll lose its stretch over time. That leaves me with the M1, which I can't figure out how to attach to the Pro-M, and FHF don't seem to have any information about that.

Long shot, but has anyone used this combination? Or recommend a better combo?

I attached a set of the FHF gear wings for my FOB harness to my Pro-M harness. It was mainly to use the cellphone pouch but could easily accommodate an M1 pouch. I used the two elastic bands that hold the front to the back. It’s not the ideal set up and I’ll likely see some webbing loops on for a better fit when I get a chance but works.
