I personally run all of my AIWB holsters with soft loops. 1 or 2 depending on the design. It allows the holsters to twist and conform to the crease in my hip/thigh when I sit/crouch etc. I do have rigid loops by companies such as JM Custom Kydex and can appreciate the rock solid feel they offer when trying to attain a solid full firing grip on the gun during draw. However, they tend to be uncomfortable for me. Lastly, IDC what brand clip you use (I get it they are convenient) but they will unintentionally come off the belt when you really really don't want them to. Take an "South Narc" ECQC class if you don't believe me. Rigid/soft belt loops do not unless they fail structurally.
