My carry 90% of the time this summer was my Springfield XD9SC in a Desantis Tuck This (with the clip switched out to a Crossbreed clip).
Conceals well under just a T-Shirt.
Now that fall is coming I will probably switch back to the Crossbreed Supertuck for my everyday carry and start carrying my full sized guns again. The subcompact is just so convenient when it is hot and humid.
Sorry for the poor pic in this one
