@Community Member if you want a setup that gives you options, C2R (British company) makes kydex insert mag pouches that give you the option to swap out bungees and Velcro flaps. I have 3x and I like them, but they are *just slightly* too narrow for PMAGs (the PMAGs fit snugly, but the over-travel prevention tab on the magazine snags about a third of the time on re-insertion). If you're only using USGI mags, they might be worth a look.
Also, C2R is super-responsive on Instagram...if you wanted to ask for a set with slightly wider dimensions, they very well might alter their spec for you.
@Community Member where did you pick them up? I looked on their site and seems like they aren't selling any pouches.
