Lets find me another holster

I currently switch between a G19 and a gen 1 Shield, both in JM Custom Kydex AIWB holsters. I want to add a Streamlight TLR7A to the 19 and start carrying a reload. JM works really well for me but they only offer their holsters with light provisions. None with a spare mag holder. They offer them separately but not built in. I haven't looked too far, too deep but I see T-Rex offers what I'm looking for. How do they rank on comfort? Any other suggesitons? Or would I be better suited to get another JM that I know will work well for me and just get an additional mag carrier?

Theres T-5 custom kydex, their papillon model iirc. Very similar to the Trex Sidecar.
