Custom CZ 75 compact in a Tagua owb or CZ RAMI in a Stoner belt slide. I have gotten away from the IWB thing. I usually wear an untucked button down shirt and don't bother too much about the gun being seen or printing. It's Indiana, who cares?
Glock 23 in a Blackhawk CQC for open carry.
Glock 23 or 22 in a IWB kydex or in a Maxpedition Fatboy bag for concealed carry
I've been known to use the factory Glock Sport Combat holster for concealed carry also.
Was carrying an XDm-40 with 4.5" barrel IWB in a Crossbreed Supertuck.
Did a straight trade for an XDs-45 though and it's working out much better for me; the XDm would print, XDs does not. My build often gets classified as "Husky" but not overly large and I continue to lose weight, so a single-stack subcompact was a no-brainer for me.
