I routinely interact with LEO's (I'm not) and they never notice. Not the beat/traffic cop type, more of the trained to notice all 'things' type.
It's imperative to have a good system that works for you (gun as well as the holster).
My Kimber Solo uses only the clipdraw - literally do not notice it's on.
Going to try the
MIC Holster and clipdraw for the Glock 26 - but the weight of the gun and added thickness make it less comfortable (and less desirable) for edc.
I have found that adding
any thickness to my CC makes the comfort go down the tube, but I'm not 'fluffy' and loosing more.
For deep concealment I LOVE the 'Smartcarry Copy' (I made my own, custom to me and various guns).
When you find yourself an inadvertent 'open carry' victim...don't panic, fix it with confidence. The quick motion to fix it will cause more suspicion, act as if it's nothing and others will follow.
