I recently received a JMCK AIWB holster for a 5" 1911. So far, I really like it. The neoprene pad (optional) helps torque the grip frame in. AIWB carry balances the weight of the gun, which makes it far more comfy to carry.
I got it with a 1.5" belt clip, which I now regret not getting on the holster for my 3" K-frames.
