Getting ready to start carrying, need some opinions on holsters.

I have a M&P shield and I'm looking for a good IWB holster. So far I've looked at the stealthGear revolution, crossbreed supertuck, and the alien gear shapeshift 4.0. I'm wanting a holster that is breathable and won't irritate my side rubbing against it. Which of these are better for that? ( I'm leaning towards the revolution ) via /r/CCW http://ift.tt/2kc24Ja
