I find this thread timely and would like to add to it. I mostly carry OWB all day at home and my favorite holster at this time is the Alien Gear Belt slide. My Shield carries the Viridian laser and that is the shell I have.

For IWB I have two day's experience with the Undertech Undercover belly band (plus a bunch of other conventional holsters I'm not super comfortable wearing). Well, it freaking works. You can tuck your t-shirt or regular shirt completely with virtually no print. But alas, I only have like 16 hours of time in it. I bought it for use when I leave the house and mostly for summer use. But I do like it so passing that on for consideration. Good luck with whatever you choose!
